摘要

Abstract The vacuum thermolysis (80–90) of the sodium salt of cyclohex-3-ene- carbaldehyde p-toluenesulfonylhydrazone (1) in silicone oil gave diazomethyl-cyclohex-3- ene (2). Pyrolytic and photolytic decomposition of this diazo compound 2 lead to methylenecyclohex-3-ene (5) and bicyclo [4.1. 0] hept-2-ene (6)(about 3: 1), while the CuCl catalyzed cleavage yielded only 5. The postulated carbene mechanism should also apply ...
