Abstract
2-Methyl-1,2,3σ2-diazaphospholes are obtained as hydrochlorides from methylhydrazones and an ecxess of PCl3 which, with longer reaction times, give the 4-dichlorophosphino-derivatives; 4-alkyl substituted diazaphospholes may be separated from their mixture with 4-unsubstituted compounds by the use of this reaction.Keywords
