Abstract
AbstractTreatment of [Et4N][Mo(CO)5(PPh2CS2)], 1 with unsaturated organic halides afforded the neutral complexes Mo(CO)5(PPh2CS2R) (R = CH2CN, 2; R = CH2C≡CH, 3). Alkylation reactions take place at the sulfur atom. Protonation of complex 2 and 3 with HBF4 produced the intramolecular cyclization products [Mo(CO)5(PPh2CS2C2H3N)][BF4], 4 and [Mo(CO)5(PPh2CS2C3H4)][BF4], 5, respectively. In complex 4 and 5, two five‐membered 1,3‐dithiolium rings formed. Protonation of 3 to 5 is not reversible, but deprotonation of 4 by n‐BuLi or PPh3 gave 2 quantitatively. Treatment of 4 with n‐Bu4NF yielded complex Mo(CO)5PPh2F, 6 and 2 with 1:1 ratio, but in the reaction of 5 and n‐Bu4NF only compound 6 was formed. All of these complexes are identified by spectroscopic methods.
