摘要

The reactivity of seven sterically hindered acid chlorides RCOCl towards ethylmagnesium bromide in the presence of cuprous chloride has been studied. In addition to the ketones RCOEt, the compounds RCOCOR, RCOR, RR, RH and R ( H) are produced by a radical reaction. The condensation of R′ MgX with iPr2CHCOCl in the presence of cuprous halide proceeds via alkylcopper species R′ Cu. MgXX′ which reacts with the acid chloride to ...
