Diazomethane related reagents

Methylene iodide and a zinc-copper couple react in ether solution to give bis-(iodomethyl)zinc zinc iodide . Closely related reagents are accessible by the reaction of zinc halides with diazomethane . These reagents have been widely used in the synthesis of cyclopropanes from olefins. Norcarane formation from cyclohexene and bis(iodomethyl)zinc was found to be second order, k = (6.3 0.5) x 10 l.mole . sec " at 0°C These findings cannot be reconciled with the intermediacy of free methylene. A one-step methylene transfer mechanism has therefore been proposed for the Simmons-Smith reaction, viz. [Pg.380]
