Abstract
Matrix photolysis of N, N-dialkyldiazoacetamides 1a–d at 7–10 K results in either the formation of C–H insertion products (in case of N, N-dimethyl and N, N-diethyl diazoamides) or almost exclusive Wolff rearrangement to ketenes (in the case of the cyclic diazoamides N- (diazoacetyl) azetidine and N-(diazoacetyl) pyrrolidine). This can be ascribed to higher activation barriers for the approach of the singlet carbene p orbital in 5 (or of the diazo ...
