Investigations on Diazo Compounds and Azides, XLII. (Diazomethyl)cyclopropenes by Electophilic Diazoalkane Substitution

The (diazomethyl)cyclopropenes 9 and 10 are formed via electrophilic diazoalkane substitution preferably of diazomethylphosphoryl compounds with cyclopropenylium salts.Either the diazomethyl compounds (7a - c) react with the cyclopropenylium salts 6a - e
