N-Alkylation of alkynyl imines 5, 6, and 8 with methyl triflate or triethyloxonium tetrafluoroborate provides the open-chain propyne iminium salts 9 and 10, the related salts 11a-e and 12b where the iminium function is a part of a heteroaromatic ring, and p-phenylene-bis(propyne iminium) salts 13a,c. The method gives access to novel propyne iminium salts in which the C,C triple bond bears an alkyl, SiMe3, or H substituent.
