Applications

Novel axially chiral Rh N-heterocyclic carbene complexes were prepared from axially dissymmetric 1,1?-binaphthalenyl-2,2?-diamine and applied in the Rh-catalyzed enantioselective hydrosilylation of methyl ketones. The enantioselective direct aldol reaction, organocatalyzed by recoverable BINAM- prolinamide derivatives can be highly accelerated by a catalytic amount of a carboxylic acid without a detrimental of the obtained enantioselectivities.

Notes

Store in cool place. Keep container tightly closed in a dry and well-ventilated place. Store away from strong oxidizing agents.
