Abstract

Dimethylketene dimethylacetal (I) is readily converted to a trisubstituted acetic ester when heated with such halides as benzoyl chloride, benzyl bromide, benzhydryl bromide and phenacyl bromide. With triphenylmethyl bromide the thermal reaction with I produces triphenylmethane, methyl methacrylate and its dimer VIII. These products are shown to arise from a concerted intramolecular thermal decomposition of the initially formed methyl, 9,, ...
