摘要：

Ylides derived from 2-acylmethyltriazolopyridinium salts (2a) -(2c) react with methyl or ethyl propiolate and with dimethyl acetylenedicarboxylate to give ylides (3a)-(3e) , (6) or (7). In some cases 1:2 adducts are formed, shown to be the novel ylides (8a)-(8d); an X-ray diffraction confirms structure (8a).
