Abstract
AbstractPropyne iminium triflates R1C(N+R3R4)CCR2 CF3SO readily react with Ph3PNPh 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 or iminio‐substituted phosphorus ylides. The configuration of these salts has been determined from NMR data and an X‐ray crystal structure analysis of salt 3h. The base‐induced elimination of the PPh3 substituent from enamino‐phosphonium salt 3a was studied. © 2005 Wiley Periodicals, Inc.
