Name: Bis(norbornadiene)rhodium (I) tetrafluoroborate. 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 Facile access to chiral 4-substituted chromanes through Rh-catalyzed asymmetric hydrogenation. Author is Tao, Lin; Zhao, Qingyang; Zhang, Xumu; Dong, Xiu-Qin.
Rh/ZhaoPhos-catalyzed asym. hydrogenation of a series of (E)-2-(chroman-4-ylidene)acetates I (R = H, Cl, F, MeO; R1 = CO2Me, CO2Et, CO2iPr) was successfully developed to prepare various chiral 4-substituted chromanes II with high yields and excellent enantioselectivities (up to 99% yield, 98% ee). Moreover, the gram-scale hydrogenation could be performed well in the presence of 0.02 mol% catalyst loading (TON = 5000) and the hydrogenation product II (R = H, R1 = CO2Et) was easily converted to access other important compounds, II (R = H, R1 = CO2H, CH2OH) which demonstrated the synthetic utility of this asym. catalytic methodol.
As far as I know, this compound(36620-11-8)Name: Bis(norbornadiene)rhodium (I) tetrafluoroborate can be applied in many ways, which is helpful for the development of experiments. Therefore many people are doing relevant researches.
