Thermolysis and photolysis of diazo-1,3-dicarbonyl compounds were investigated as a fuction of methanol concentration.As the methanol concentration decreased, methyl group migration increased concomitant with the suppresion of O-H insertion into methanol, whereas aryl group migration was essentially uanaltered with the methanol concentration.The results are interpreted as indicating that aryl migration occurs directly from the excited state of diazo compounds, but that methyl migration takes place un the singlet carbene in competition with O-H insertion.
