A convenient synthesis and some characteristic reactions of novel propiolamidinium salts

Starting from N,N,N,N,N,N-hexaalkylguanidinium chlorides and terminal alkynes, a series of new orthoamide derivatives of alkynecarboxylic acids were prepared. The orthoamides were converted into propiolamidinium chlorides by reaction with benzoyl chloride
