The reactions of the α-lithio derivative of diethyl methylphosphonate with various organic halides are described. The half-reduction of gem-dihalocyclopropanes has been achieved with this reagent. The same reagent gives bibenzyl and tetraphenylethane from benzyl bromide and benzhydryl chloride respectively. The deprotonation-metallation process is observed in the reactions of cinnamyl chloride and of trans-β-bromostyrene, in which 3-chloro-1,6-diphenyl-1,5-hexadiene and 1,4-diphenyl-3-buten-1-yne are produced respectively.
