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.
甲基三氟甲磺酸酯或三乙基氧鎓四氟硼酸盐对炔基亚胺5、6和8进行N-烷基化反应,生成开链丙炔亚胺盐9和10,相关盐类11a-e和12b,其中亚胺功能团为杂芳环的一部分,以及对苯撑双(丙炔亚胺)盐13a,c。该方法可制备新型丙炔亚胺盐,其中的碳-碳三键带有烷基、三甲基硅基或氢取代基。
