CIDNP as a tool to unveil the reaction mechanism: interaction of mixed phosphonium–iodonium ylide with p-methoxyphenylacetylene

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

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