Electric Literature of C14H8BF4Rh. Aromatic compounds can be divided into two categories: single heterocycles and fused heterocycles. Compound: Bis(norbornadiene)rhodium (I) tetrafluoroborate, is researched, Molecular C14H8BF4Rh, CAS is 36620-11-8, about Rhodium-catalyzed asymmetric hydrogenation of exocyclic α,β-unsaturated carbonyl compounds. Author is Yang, Jiaxin; Li, Xiuxiu; You, Cai; Li, Shuailong; Guan, Yu-Qing; Lv, Hui; Zhang, Xumu.
A highly enantioselective hydrogenation of exocyclic α,β-unsaturated carbonyl compounds I (X = O, CH2, N-Boc; L = bond, CH2; R = Ph, 4-MeOC6H4, 2-naphthyl, etc.) catalyzed by Rh/bisphosphine-thiourea (ZhaoPhos) has been developed, giving the corresponding α-chiral cyclic lactones, lactams and ketones II with high yields and excellent enantioselectivities (up to 99% yield and 99% ee). Remarkably, the hydrogen bond between the substrate and the catalyst plays a critical role in this transformation. The synthetic utility of this protocol has been demonstrated by efficient synthesis of chiral 3-(4-fluorobenzyl)piperidine, a key chiral fragment of bioactive mols.
Different reactions of this compound(Bis(norbornadiene)rhodium (I) tetrafluoroborate)Electric Literature of C14H8BF4Rh require different conditions, so the reaction conditions are very important.
