Grignard reaction grignard reagents. the grignard reaction is the addition of an organomagnesium halide (grignard reagent) to a ketone or aldehyde, to form a tertiary or secondary alcohol, respectively., kumada coupling. the kumada coupling was the first pd or ni-catalyzed cross coupling reaction, developed in 1972. the coupling of grignard reagents with alkyl, vinyl or aryl halides under ni-catalysis provides an economic transformation, but the reaction is limited to halide partners that do not react with organomagnesium compounds..

It was demonstrated that the magnesium (s)‐3,3′‐dimethyl binolate enantioselectively catalyze the direct vinylation of aldehydes with the deactivated vinylmagnesium bromide by bis[2‐(n,n′‐dimethylami..., it is likely that reactions of magnesium metal with organic halides rx in ether solvents are typical metallic corrosions in which the stabilization of mg 2+, substantially through its coordination by the solvent, drives its loss from the metal and consequently the reductions of rx and reaction intermediates such as r at the metal surface. although alkyl halides form grignard reagents through ....
