The combination of the readily available chiral bisphosphine ligand Difluorphos with [Ir(COD)Cl]2 in THF resulted in a highly efficient catalyst system for asym. hydrogenation of quinolines at quite low catalyst loadings (0.05-0.002 mol%), affording the corresponding products with high enantioselectivities (up to 96%), excellent catalytic activities (TOF up to 3510 h-1) and productivities (TON up to 43000). The same catalyst was also successfully applied to the asym. hydrogenation of trisubstituted pyridines with nearly quant. yields and up to 98% ee. In these two reactions, the addition of I2 additive is indispensable; but the amount of I2 has a different effect on catalytic performance.

The complex of AgF and (R)-DIFLUORPHOS has been shown to be an effective catalyst for the asym. Sakurai-Hosomi allylation of simple ketones. A significant improvement of the reactivity was observed by using THF as the solvent. The catalyst turnover was increased by addition of 1 equiv of MeOH. AgF and (R)-DIFLUORPHOS predominantly formed a 1:1 complex that provided high enantioselectivity. This catalyst system can be applied to various simple ketones, and corresponding tertiary homoallylic alcs. were obtained with excellent enantioselectivities. Only 1,2-adducts were obtained from both acyclic and cyclic conjugate ketones. The regio-, diastereo-, and enantioselective crotylation has also been achieved. E- or Z-crotyltrimethoxysilane gave a similar diastereomer ratio with high enantioselectivities. This finding introduces the utility of racemic allylsilanes for the enantioselective Sakurai-Hosomi allylation reaction.
