Abstract
Alkylation reactions at the S atom of the anionic PPh2C(NPh)S- ligand coordinated to a tungsten pentacarbonyl group afford the neutral complexes W(CO)5PPh2C(NPh)SR (4, R = CH2C⋮CH; 5, R = CH2C⋮N; 6, R = CH2CONH2; 7, R = CH2CHCH2; 8, R = CH2CO2Me). Protonation of 4 with HBF4 at room temperature causes cyclization to the cationic which contains a (thiazoliumyl)diphenylphosphine ligand. Similarly, protonation reactions of 5 and 6 with HBF4 give the cationic and the neutral (12), respectively, both of which contain (thiazoliumyl)diphenylphosphine ligands. The structures of 10 and 12 are determined by X-ray diffraction analyses.
