Abstract

1-(Alk-1-ynyl)-2,3-diphenylcyclopropenium perchlorates 7 have been prepared via the generation of (alk-1-ynyl)chlorocarbenes 3 from 1,1-dichloroalk-2-ynes 1 or 3-bromo-1,1,1-trichloro-3-phenylpropane 2 by the interaction with ButOK in the presence of tolan followed by the treatment of the reaction mixture with perchloric acid, whereas the treatment of the reaction mixture with HBr resulted in (2-bromoalk-1-enyl)cyclopropenium bromides 9
