日期:1980.1
The regiochemistry of diazomethanecycloadditions with simple alkylethylenes, heretofore not reported, was investigated in the simplest case, diazomethane and propene. The products were 3-and 4-methylpyrazolines in 7.4/1 ratio, in accord with the diradical mechanism. This mechanism also accounts for the abnormal orientation in intramolecular cases and with bridgehead olefins.
