Digermylplatinum(II) organometallic rings L2PtGe(Me2)EGeMe2 [E = N-, O, S, (η-C5H4)2Fe]

The synthesis, reactivity, and characterization of the digermylplatinum(II) linear complexes (ClMe2Ge)2Pt(PPh3)2 (1) and (ClMe2Ge)2Pt(diphos) (2) and cyclic complexes (diphos)PtGe-(Me2)EGeMe2 [E = S (3), -NPh (4), (η5-C5H4)Fe(η5-C 5H4) (5), O (6)] are reported. The chemistry of 2-6 is illustrated through their reactions with phenylacetylene and N-methyltriazolinedione. Complexes 3 and 6 give double germylation of these unsaturated systems, while 2, by reaction with triazolinedione, gives the monogermylated complex Me2-(Cl)GePt(Cl)diphos and the dimer of the germylated heterocycle Me2GeNC(O)N(Me)C(O)N.

Direct Synthesis of Organobromogermanes from Methylenebromide

From the copper-catalyzed reaction of germanium powder with dibromomethane at 310 deg C a mixture of alkylbromogermanes is obtained.The major products are CH3GeBr3, Br3GeCH2Br (1), CH2(GeBr3)2 (2) and (CH2GeBr2)3 (3).The product distribution parallels the analogous reaction with dichloromethane reported previously.All compounds were characterized by analytical and spectroscopic data, and can be converted into the corresponding hydrides. - Keywords: Alkylbromogermanes, Synthesis, CVD Feeding Gas, Germanium/Copper Mixtures

Germacyclopentanes via cycloadditions of free dimethylgermylene to styrenes

Free Me2Ge gives cycloadditions with 2 mol of α-substituted styrenes via a regiospecific but not stereospecific mechanism. Equal amounts of syn/anti 3,4-diphenylgermacyclopentanes are formed in good yield, those arising from α-substituted styrenes bearing additional substituents in these positions, and no 2,5- or 2,4-substituted rings. The 4,4,5,5-Ph4 derivative has an extraordinarily strained five-membered ring with a very long C3-C4 bond (1.626 A?) and αC-Ge-C = 90.3°. Styrenes without a =CH2 group as well as a number of other olefins do not react rapidly enough. A two-step mechanism involving an 1:1 adduct is suggested.
