Fr. Kreissl et al., THIOMETHYLATION OF THE METAL-CARBON MULTI PLE BOND OF CARBYNE AND CARBENE COMPLEXES OF MOLYBDENUM AND TUNGSTEN, Chemische Berichte, 126(7), 1993, pp. 1609-1614
Carbyne complexes of molybdenum and tungsten react with dialkyl(methyl
thio)sulfonium tetrafluoroborate in a stepwise addition of the alkylth
io cation to the metal-carbon multiple bond yielding dicationic eta3-d
ithiomethyl complexes.
