Introduction of a phosphorus ylide moiety into [η2-(ω-hydroxy)alkenyl]chromium(0) carbene complexes with Ph3PCCO and consecutive Wittig alkenations with 2-alkynals. Part 12: the chemistry of metallacyclic alkenylcarbene complexes

11 Chromium, molybdenum and tungsten

“…All complexes were characterised in solution by one-and two-dimensional NMR spectroscopy. 163 5-Phenyl-1,2-dithiole-3-thione was synthesised from a series of molybdenum dithiopropiolato complexes, for example [(g 5 -C 5 H 4 R9)Mo(CO) 2 (g 2 -S 2 CCMCPh)]. 164 The preparation and characterisation of a series of deuterium-labelled [(fulvene)M(CO) 3 ] (M = Cr, Mo) complexes was reported.…”
