摘要: Isocyanides (C≡NR) and alkynes react with electron-rich d6 Mo-, W- or Re-phosphinic centres (M) to give complexes short metal-carbon bond distances, where the derived organic ligand may present at least a partial carbene character. In these reactions undergo metal-centred rearrangements involving hydrogen-migration vinylidene (M=C=CHR), allene Open image in new window alkynyl (M-C≡CR)
