Bis(dimethylgermyl)alkane ruthenium tetracarbonyls Me2Ge(CH2)nGe(Me2)Ru(CO)4 (n = 1, 2) are obtained by reaction of bis(dimethylgermyl)alkanes Me2(H)Ge(CH2)nGe(H)Me2 (n = 1, 2) with Ru3(CO)12 under UV irradiation, or by heating. Various CO substitution reactions with phosphines by heating and cleavage reactions with protonic, electrophilic, nucleophilic or radical reagents are described. XO oxides

This work concerns the synthesis of [bis(dimethylgermyl)alkane]bis(triphenylphosphine)platine(II) and -(diphos)platine(II) Me2Ge(CH2)nGe(Me2)PtL2 (n = 2, L = PPh3 (1), diphos (2); n = l, L = PPh3 (3), diphos (4) and (tetramethyldigermyl)bis(triphenylphosphine)platine(II) and -(diphos)platine(II) Me2GeGe(Me2)PtL2 (L=PPh3 (5), diphos (6). 3 and 5 are obtained by cyclization of bis(dimethylgermyl)alkanes Me2(H)Ge(CH2)nGe(H)Me2 (n = 1 or 2) or 1,1,2,2-tetramethyldigermane Me2(H)GeGe(H)Me2 with (Ph3P)2PtC2H4. The polymeric structures [Me2Ge(CH)2)nGe(Me2)Pt(PPh3)2]m (n = 1 or 2) react with diphos to give the monomer complexes 2 or 4. IR and NMR examinations are reported. Various cleavage reactions with halogens and organic halides are described. Reactions of 2 with phenylacetylene and 1,2,4-triazolinediones afford new heterocycles arising- from formal addition of these unsaturated systems across the Ge-Ge bond of the tetramethyldigermetane Me2Ge(CH2)2GeMe2.
