Direct CH Bond Activation of Benzoxazole and Benzothiazole with Aryl Bromides Catalyzed by Palladium(II)-N-heterocyclic Carbene Complexes

Herein, we report that a series of novel palladium(II)-NHC complexes (NHC=N-heterocyclic carbene) were synthesized. The structures of all novel complexes were characterized by H-1 NMR, C-13 NMR, FT-IR spectroscopy and elemental analysis techniques. These palladium(II)-NHC complexes were tested as efficient catalysts in the direct CH bond activation of benzoxazole and benzothiazole with aryl bromides in the presence of 1 mol% catalyst loading at 150 degrees C for 4 h. Under the given conditions, various aryl bromides were successfully applied as the arylating reagents to achieve the 2-arylbenzoxazoles and 2-arylbenzothiazoles in acceptable to high yields.

Tuning the heat resistance properties of polyimides by intermolecular interaction strengthening for flexible substrate application

Intrinsic polyimides (PIs) with high glass transition temperature (T-g), excellent thermal stability, and favorable mechanical properties have been in great demand in recent years with the rapid development of flexible displays. In this work, an interchain-interaction strengthener has been introduced to obtain PIs with improved thermal resistance and stability. Benzimidazole-based diamines imparting rigidity, conjugation, crosslinking, and especially hydrogen bonding have been incorporated into benzoxazole-polyimide. Frequency shifts in the IR bands spectra of C=O and N-H bonds were indicative of strong hydrogen bonding in benzimidazole-incorporating PIs, resulting in an increase in T-g from 333 degrees C to 442 degrees C. Furthermore, because of more extensive hydrogen bonding, PIs containing bis-benzimidazole units exhibited much higher crystallinity and T-g than those containing mono-benzimidazole units. The 5% weight loss temperature (T-d(5)) was above 550 degrees C because of the rigidity of the conjugated structure and the tightly packed state of the polymer chains. T-g and T-d(5) of PIs annealed in air were higher than those of samples annealed in vacuo, whereas the opposite trend was seen in crystallinity and mechanical properties. Finally, we delineated the effects of intermolecular interaction strengthener and annealing atmosphere on the properties of PIs, which may be helpful for the future design of flexible PI substrates.

Synthesis and reactivity of an osmium(iii) aminoguanidine complex

The biological activities of aminoguanidine (GNH(2)) and its derivatives have been extensively studied due to their properties as radical scavengers and antioxidants. Some of their biological activities may result from their binding to various metals present in biological systems. However, the reactivity of coordinated aminoguanidines has not been investigated. We report herein the synthesis, structure and reactivity of a novel osmium(iii) complex bearing the parent aminoguanidine, mer-[Os{NHC(NH2)(NHNH2)}(L)(CN)(3)](-) (OsGNH(2), HL = 2-(2-hydroxyphenyl)benzoxazole). The antioxidant properties of OsGNH(2) have been investigated by reactions with various oxidants, including O-2, H2O2, m-chloroperbenzoic acid (m-CPBA) and Ce(iv). Various osmium products are produced, which depend on the type of oxidant used. OsGNH(2) is readily oxidized by O-2 or H2O2 under ambient conditions to afford an osmium(iii) formamidine complex, [Os-III(NH2CNH)(L)(CN)(3)](-) (OsFA, FA = formamidine). With m-CPBA, the nitrosyl complex, mer-[Os(NO)(L)(CN)(3)](-) (OsNO), is formed instead. On the other hand, the nitrido complex mer-[Os(N)(L)(CN)(3)](-) (OsN) is produced when the one-electron oxidant (NH4)(2)[Ce-IV(NO3)(6)] (Ce(iv)) is employed. The molecular structures of OsGNH(2) and OsFA have been determined by X-ray crystallography. The oxidation of OsGNH(2) to OsFA by O-2 or H2O2 is proposed to go through initial dehydrogenation to give a diazoamidine intermediate. In the oxidation by m-CPBA and Ce(iv), it is proposed that the initially formed OsFA is further oxidized to OsNO and OsN, respectively, via osmium(iii) hydrogen cyanamido and osmium(iv) cyanoimido intermediates.

A theoretical prediction about harnessing ESPT process for HBO derivatives

The different excited-state behaviors involved in excited-state proton transfer (ESPT) process of a series of 2-(2-hydroxyphenyl)benzoxazole (HBO) derivatives have been theoretically investigated. The primary bond lengths and bond angles were analyzed. Coupling with the infrared (IR) vibrational spectra, we confirmed that the intramolecular hydrogen bond O-HN should be strengthened in the S-1 state, which might provide the possibility for ESPT reaction, whereas introducing the fused rings may weaken the hydrogen bond in excited state. By investigating the vertical excitation process, the charge redistribution was explored. It is found that the electron-accepting -NO2 and -COOH would facilitate the ESPT reaction. With adding fused rings to HBO, less charge transfer exists in the transition process, which can reasonably explain the weakening hydrogen bond phenomenon in excited states. Via constructing the potential energy curves of both S-0 and S-1 states, we further confirm that electron-accepting substitutions could promote the ESPT process for HBO systems. And fused rings do inhibit ESPT reaction to a great extent. We believe this work not only elaborates the different excited-state proton transfer behaviors for a series of HBO derivatives but also presents a new harnessing ESPT process through substitutional effects.

Facile Protocols towards C2-Arylated Benzoxazoles using Fe(III)-Catalyzed C(sp(2)-H) Functionalization and Metal-Free Domino Approach

Considering their growing attention in the field of medicinal chemistry and drug-discovery research, the facile and convenient approaches towards the preparation of 2-aryl benzoxazole derivatives have been described. The transformation is accomplished by using Fe(III)-catalyzed C-H activation of benzoxazoles with boronic acids to obtain a wide range of C2-arylated benzoxazoles in high yields. The developed method excludes the formation of self-coupling compounds as side products. On the other hand, the synthesis of the products is also achieved via a metal-free domino protocol by the reaction between 1-nitroso-2-naphthol and acetophenones using catalytic amounts of CBr4 in the presence of Cs2CO3 as base. The devised tandem method avoids the use of pre-activated alpha-haloketones as substrates. Due to their immense impact in marketed drugs and molecules under clinical trial, the described method can be a powerful tool for their synthesis which restricts the use of precious metals as catalyst.

Unexpected Ring Opening During the Imination of Camphor-Type Bicyclic Ketones

A new ring opening reaction was found while attempting to isolate the imines from ortho-heteroatom substituted anilines and camphor-like bicyclic ketones. The benzoazoles containing a cyclopentanemethyl group at position 2 of the heterocycle were isolated instead of the expected imines. The detailed study of the transformation, including EPR experiments, revealed the most probable radical mechanism. The proposed reaction pathways were confirmed by quantum chemical calculations. The dichotomy of 1-2 and 2-3 bonds cleavage is discussed together with the evaluation of the stereochemical outcome of the reactions. The benzoazoles obtained via the new reaction are of particular interest for the medicinal chemistry.
