Abstract

The reaction of a series of thioimides with phosphorus ylides, in a manner analogous to the Wittig reaction, has been examined. The resulting reaction products represent potentially valuable intermediates in tetrapyrrole pigment syntheais. In addition to the desired thio- Wittig-type coupling reaction, the presence of two competing reaction pathways, Salkylation and ondation/reduction, has been obeerved with certain substrates. These empirical ...
