Reactions of iodinated vinylidene complexes generated from 1-iodo-1-alkynes and W(CO)5(thf).
We have succeeded in generating iodinated tungsten vinylidene complexes from 1-iodo-1-alkynes and W(CO)5(thf), and have employed these complexes for two types of synthetically useful reactions, that is, 6pi-electrocyclization for o-(iodoethynyl)styrenes and endo-selective cyclization for omega-iodoacetylenic silyl enol ethers.
