Abstract

Abstract PHIP (parahydrogen-induced polarisation) effects in the 1 H NMR spectra of the products of Rh-complex-catalysed alkyne hydrogenation brings to light the fact that the cis– trans isomerisation of the formed olefin occurs through the formation of a σ-bonded intermediate stabilised by the reversible addition of a hydrogen molecule at the metal centre.(© Wiley-VCH Verlag GmbH & Co.
