Nickel-catalysed substitution reactions of allylic carbonates with aryl- and alkenyl-borates
Abstract
Substitution reactions of 1,3-disubstituted allylic carbonates 3 with aryl- and alkenyl-borates 4 are catalysed by [NiCl2(dppf)][dppf = 1,1′-bis(diphenylphosphino)ferrocene], and in the case of the cyclic carbonate 7, the reaction proceeds with complete inversion.
