Cyclopentadienyl tungsten complexes with thiocarboxylate and thiosulfonate ligands: Structures of CpW(CO)3SCOPh and CpW(CO)3SSO2-4-C6H4Cl

Treatment of the hydrosulfido tungsten complex CpW(CO) 3 SH with acid chlorides (RCOCl) or sulfonyl chlorides (RSO 2 Cl) affords CpW(CO) 3 SCOR ( 1 ) [R = Me ( a ), CH 2 Cl ( b ), Ph ( c ), 4-C 6 H 4 NO 2 ( d )] and CpW(CO) 3 SSO 2 R ( 2 ) [R = Me ( a ), Ph ( b ), 4-C 6 H 4 Cl ( c ), 4-C 6 H 4 NO 2 ( d )], respectively. The novel complexes, 1 and 2 , were fully characterized by elemental analyses, IR and 1 H NMR spectroscopy. The solid state structures of CpW(CO) 3 SCOPh ( 1c ) and CpW(CO) 3 SSO 2 -4-C 6 H 4 Cl ( 2c ) were determined by an X-ray crystal structure analysis.
