Abstract

Abstract The electrophilic character of carbenoïds can be activated by addition of organocopper reagents (RCu, R 2 CuM, or RCuZM), forming an unsymmetrical cuprate. Internal substitution of the carbenoïd halogen by the R group leads to a new alkylated unsymmetrical cuprate reagent. R can be primary, secondary, or tertiary alkyl, aryl, thiophenyl.
