EN

Chloroform reacts with an excess of methyl methacrylate in the presence of 50% aq NaOH and benzyltriethylammonium chloride (TEBA) as a catalyst (phase transfer catalysis, PTC) to give a mixture of dichlorocarbene and trichloromethyl anion adducts, 1 and 2, respectively. These additions proceed as parallel processes, there is a slow conversion of 2_ 1, which proceeds as an intramolecular process.
