Schwefel(IV)-verbindungen als liganden: IV. O-silylierung von SO2-komplexen

Abstract The sulfur dioxide complexes mer,trans -M(CO) 3 (L) 2 (η 1 -SO 2 ) (L = PPh 2 Me, P(OMe) 3 ; M = Mo, W), fac -M(CO) 3 (dppe)(η 2 -SO 2 ) (M = Mo, W), mer -M(CO) 3 -(dmpe)(η 1 -SO 2 ) (M = Cr, Mo, W), mer -M(CO) 3 (dppe)(η 1 -SO 2 ) (M = Mo, W), and trans -M(CO) 2 (dppe)(P-i-Pr 3 )(η 1 -SO 2 ) (M = Mo, W) react with Me 3 SiOSO 2 CF 3 to give the corresponding O -silylated derivatives. The new compounds were characterized by IR, 29 Si and 31 P NMR spectroscopy.
