✦ Synopsis

Abstract

Tributylphosphane reacts with DMAD to give the crystalline adduct 2 which is stabilised by extensive delocalisation and whose formation involves an unusual rearrangement. The isomeric structure 7 for the previously reported adduct with triphenylphosphane is supported by ^13^C NMR spectroscopy. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003)
