The regiochemistry of diazomethane cycloadditions 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.
在最简单的情况下,用重氮甲烷和丙烯研究了重氮甲烷与简单烷基乙烯的环加成反应的区域化学。产物为7.4 / 1比例的3-和4-甲基吡唑啉,符合双自由基机理。该机制还解释了分子内情况和桥头烯烃的异常取向。
