Magnesium carbenoids were generated from aryl 1-chloroalkyl sulfoxides with i-PrMgCl in THF at low temperature in quantitative yields. The magnesium carbenoids were found to be reactive with N-lithio alkylamines to afford an olefin, which was derived from dimerization of the magnesium carbenoid, in moderate yield. On the other hand, reaction of the magnesium carbenoids with N-substituted N-lithio...
Treatment of 1-chloroalkyl phenyl sulfoxides with a Grignard reagent at low temperature afforded magnesium carbenoids in quantitative yields. The magnesium carbenoids were found to be reactive with N-lithio alkylamines and N-lithio arylamines. The reaction with N-lithio alkylamines afforded an olefin, which was derived from dimerization of the magnesium carbenoid, in moderate yield. The reaction with...
