CS2 insertion into a gold–carbon bond. First syntheses and characterization of 2,2-diacetylethylene-1,1-dithiolato complexes. Crystal structure of [N(PPh3)2][Au{η2-S2C
C(COMe)2}2]†
Abstract
The reaction of [N(PPh3)2][Au(acac)2] (acac = acetylacetonate) with CS2 gives [N(PPh3)2]2[Au2{µ2:η2-S2CC(COMe)2}2], which reacts with PhICl2 to give [N(PPh3)2][Au{η2-S2C
C(COMe)2}2], for which the crystal structure is determined; these are the first characterized 2,2-diacetylethylene-1,1-dithiolato complexes of any element.
