## Abstract Propyne iminium triflates R^1^C(N^+^R^3^R^4^)CCR^2^ CF~3~SO readily react with Ph~3~PNPh to form 1:1 adducts which formally result from a metathetical addition of the phosphorane imine across the triple bond of the alkyne. These adducts are best described as enamino‐phosphonium salts

The reaction of a carbamoylsilane with aldehydes or ketones affords a-siloxyamides. The addition reaction is catalyzed by fluoride ion (TBAT, 25-50°C), but proceeds in the absence of catalyst at higher temperatures (50-100°C).
