Abstract

In situ acquisition of the reaction between benzoyl phosphonium–iodonium ylide and p-methoxyphenylacetylene in an NMR spectrometer reveals the CIDNP effect in 31P and 1H NMR spectra of major products, substituted furan (emission) and phosphonium salt (enhanced absorption). The mechanism of products formation via radical pairs is discussed.
