Unprecedented reactions of alkynes with η2-CS2 metal complexes

Abstract

Alkynes react with [Mo(η5-C5H5)22-CS2)](1) to afford heterocycle derivatives [(η5-C5H5)2[graphic omitted]R][(2) R = CF3; (3) R = CO2Me] and [(η5-C5H5)2[graphic omitted]R][(4) R = CO2Me], and both (2) and (3) react with HC[triple bond, length half m-dash]C–CN to yield [(η5-C5H5)[graphic omitted]R}][(5) R = CO2Me; (6) R = CF3], while treatment of (1) with HC[triple bond, length half m-dash]C–CN gives an unprecedented metallacycle [(η5-C5H5)2Mo(C10H3N3S2)](7), corresponding to the addition of three alkynes to CS2; the structures of (4), (5), and (7) have been established by X-ray crystallography.
