The titled reaction proceeds smoothly under mild conditions to give corresponding 1-alkylcycloalkenes in excellent yields. The overall reaction provides a convenient synthetic procedure of cycloalkenes for cycloalkanones, with various alkyl substituents readily available by means of hydrobortation.

Stereoselective preparation of trisubstituted olefins can be easily performed from an Z/E-mixture of enol phosphates by reacting only the E-isomer with a Grignardreagent in the presence of Fe(acac) 3 . This procedure combines a kinetic differentiation and a stereoselective reaction. The coupling is very chemoselective in the presence of an alkyl chloride, an ester, a ketone or a nitrile.
