Lithium diorganocuprates are now widely used in conjugate additions to a,a-unsaturated car-bony1 compounds' and in coupling reactions with alkyl halides2, allyli~acetates~, and other compounds possessing good leaving groups. Here we report a new reaction of lithium dialkylcuprates which is formally
Sumnary : Oiethylphosphoryl methanesulphonates 2 and 4 were readily converted into cu,p-unsa- \_ \_ turated sulphonates by successive treatment with n-8uLi and aldehydes or ketones. Epoxidation of esters 5 with t-butyl hydroperoxide in the presence of Triton 6 yielded stereoselectively \_ salts of t
