H. Bricout et al., EFFICIENT COUPLING REACTIONS OF ALLYLAMINES WITH SOFT NUCLEOPHILES USING NICKEL-BASED CATALYSTS, Chemical communications, (15), 1997, pp. 1393-1394
Substitution reactions of N,N-diethylallylamine 1 with soft nucleophil
es such as active methylene compounds 2a-c and piperidine 5 proceed mu
ch more rapidly in the presence of Ni(dppb)(2) [dppb = 1,4-bis(dipheny
lphosphino)butane] as catalyst than with comparable palladium systems.
