Abstract

INTRODUCTION Ethynyl cation 2 was generated for the first time in 1988 by the #?-decay of a tritium substituted alkyne 1 (Scheme l).' ... Ethynyl cations have eluded generation by solvolytic procedures.2 Other potential precursors for the generation of ethynyl cations are ethynyldiazonium salts. However, theoretical calculations have shown that the unimolecular, thermal dediazoniation of the parent ethynyldiazonium ion is greatly endothermic and kinetically hindered.' ...
