Product Details of 92-86-4. Recently I am researching about SIZE DEPENDENCE; MEDIATED SYNTHESIS; CONCISE SYNTHESIS; RADICAL-CATION; BEARING 3; CARBON; CYCLOPARAPHENYLENES; NANORINGS; DICATIONS; N=8-13, Saw an article supported by the Japan Society for the Promotion of Science (JSPS) KAKENHIMinistry of Education, Culture, Sports, Science and Technology, Japan (MEXT)Japan Society for the Promotion of ScienceGrants-in-Aid for Scientific Research (KAKENHI) [18H01962, 16H06352]; Tokyo Chemical Industry Co.; Super Computer Laboratory, Institute for Chemical Research, Kyoto University. Published in AMER CHEMICAL SOC in WASHINGTON ,Authors: Kawanishi, T; Ishida, K; Kayahara, E; Yamago, S. The CAS is 92-86-4. Through research, I have a further understanding and discovery of 4,4′-Dibromobiphenyl
Selective and large-scale synthesis of [8]-cycloparaphenylene (CPP) was achieved in seven steps starting from commercially available 4-bromo-4′-hydroxybiphenyl and 4,4’dibromobiphenyl. The key unsymmetrical tetraring unit, 4-bromophenyl and 4′-bromobiphenyl-substituted cis-1,4-bis(triethylsiloxy)-2,5-cyclohexadiene-1,4-diyl (5fA), was synthesized on an similar to 50 g scale by stereoselective cis-addition of 4-bromo-4′-lithiobiphenyl to 4-(4-bromophenyl)-4-hydroxy-2,5-cyclohexadienl-one, which was synthesized on an similar to 100 g scale. Platinum-mediated selective dimerization of the four-ring unit 5fB and subsequent reductive aromatization of the cyclohexadiene-diyl by H2SnCl4 gave 2 g of [8]CPP in 6.6% overall yield (10.2% on small scale).
