SULFENAMIDES AS LIGANDS IN TRANSITION-METAL CHEMISTRY PENTACARBONYL(SULFENAMIDE)CHROMIUM(0) COMPLEXES

The complexes Cr(CO)5(R'SNR2) [R' = CH3; NR2 = N(CH3)2, N(C4H8)O. R' = C6H5; NR2 = N(CH3)2, N(C4H4)O, N(CH2-C6H5)2, N(C6H11)2] have been prepared by reaction of the sulfenamides with Cr(CO)5. THF and characterized by analytical and spectroscopic methods. The IR, H-1-NMR, UV-VIS, and mass spectra of the complexes support the coordination of the sulfenamide via the sulfur atom. pi-acceptor abilities of sulfenamides in the prepared coordination compounds, determined from IR and UV-VIS data, were compared with those of other divalent sulfur conpounds.
