The use of dad (and bian) ligands in the stabilization of main-group complexes, in particular metal–metal-bonded compounds, as well as the small molecule reactivity of these (low-valent) metal complexes, is summarized.

The reaction of bis(2,3,4,6-tetra-0-acetyl-β-D-glucopyranosyl)disulfide with (Ph3P)2Pt(C2H4) gives cis-di(2,3,4,6-tetra-0-acetyl-l-mercapto-β-D-glucopyranosid)bis(triphenylphosphane)platinum (II). A dithiocarbimato complex (Ph3P)2Pt(S2CNR) has been isolated from cis-(Ph3P)2PtCl2, CS2 and 1-0-Methyl-2-amino-2-deoxy-4,6-benzyliden-α,β-D-glucopyranoside. Metal complexes with metal-carbon bonds have been prepared by oxidative addition of monosaccharide halides to (Ph3P)2Pt(C2H4) or to cobalt(I) cobaloxime, respectively. From the reaction of (Ph3P)2Pt(C2H4) with 2,3,4,6 -Tetra-O-acetyl-α-D-glucopyranosyl-bromide the anomers trans-(α- and β-glucopyranosyl) Pt(PPh3)2Br have been obtained. This indicates a radical reaction.
