摘要：

N-Pyridinium dichlorophosphinomethylides disproportionate to generate bis(N-pyridiniumylidyl)phosphenium chloride which undergoes I, 5-electrocyclization to give 2-phosphaindolizines. In one-pot synthesis N-(alkoxycarbonylmethyl)pyridinium bromide reacts with PCl3 in presence of Et3N to form 2-phosphaindolizine. (C) 1999 Elsevier Science Ltd. All rights reserved.
