Abstract:

Metal-carbynes RC-MCO4BrTriple bond with diacetylenes give specific phenols in good yield. The reactions take only a few minutes at or below room temperature. Metal-carbynes, unlike metal-carbenes, have rarely been considered reagents for organic synthesis although those illustrated by structre 1 have been known for a dozen years and are fairly easy to prepare. We reported recently that a number of tungsten metal-carbynes, by polymerizing a variety of acetylenes and cyclic alkenes, behave as though they were reactive metal-carbenes. We are reporting here that, as illustrated in equation 1, they combine stoichiometrically with a variety of diacetylenes to give specific phenols in a seemingly general process that is simple to carry out. Originator supplied keywords include Acetylenes, Metal-Carbynes, Metallacycles, Polyacetylenes.
