Phenyltrichlorogermane synthesis by the reaction of chlorobenzene and the dichlorogermylene intermediate formed from elemental germanium and tetrachlorogermane
Okamoto, Masaki,Asano, Takuya,Suzuki, Eiichi
, p. 5583 - 5585 (2001)
Phenyltrichlorogermane was synthesized with high selectivity, 96%, from elemental germanium, tetrachlorogermane, and chlorobenzene using no catalyst, almost all germanium and tetrachlorogermane being converted. Dichlorogermylene was formed as a reaction intermediate by the reaction of germanium with tetrachlorogermane and inserted into the C-Cl bond of chlorobenzene to yield phenyltrichlorogermane.
Reaction of germanium tetrachloride with chloro(phenyl)silanes in the presence of aluminum chloride
Zhun',Sbitneva,Chernyshev
, p. 867 - 869 (2005)
The effect of the quantity of aluminum chloride on the direction and depth of reaction of germanium tetrachloride with chloro(phenyl)silanes of the general formula PhnSiCl4-n (n = 1 - 3) was studied to show that radical exchange between germanium and silicon is initiated only if the mixture contains no less than 2.5-5 wt % of aluminum chloride. With trichloro(phenyl)silane, the radical exchange is initiated at 5 wt % of aluminum chloride and results in exclusive formation of trichloro(phenyl)germane. The reactions of GeCl4 with dichlorodiphenylsilane and chlorotriphenylsilane in the presence of 2.5-7.5 wt % of aluminum chloride give dichlorodiphenylgermane as the major product, and at AlCl3 concentrations of above 10 wt % the major product becomes to be trichloro(phenyl)germane.

, p. 280 - 284 (2014/04/17)
Reaction of tetrachlorogermane with 2-thienylchlorosilane and methyl(2-thienyl)dichlorosilane in presence of AlCl3 is studied. It was shown that in the reaction with 2-thienyltrichlorosilane 2-thienyltrichlorogermane mainly formed, while in the reactions with methyl(2-thienyl)dichlorosiulane aromatic germaniumcontaining compounds like 2-thienyltrichlorogermane and di(2-thienyl)dichlorogermane were obtained. Quantum-chemical calculations showed that the reaction of chlorine atoms exchange in GeCl4 with aromatic moiety formed from arylchlorosilanes in the presence of AlCl3 proceeds through a four-membered activated complex.
Reactions of organochlorosilanes with chloro-and organogermanes in the presence of aluminum chloride
Zhun,Sbitneva,Polivanov,Chernyshev
, p. 1564 - 1570 (2008/02/09)
The effect of substituents at the silicon and germanium atoms in reactions of organochlorosilanes with chloro-and organogermanes in the presence of aluminum chloride was studied. The only occurring process is the exchange of the chlorine atoms at Ge for the phenyl groups from Si; an increase in the number of methyl groups or chlorine atoms at Si promotes formation of phenyltrichlorogermane, and an increase in the number of phenyl groups or replacement of the chlorine atom at the Si atom by hydrogen leads to the formation of di-and triphenylchlorogermanes. Neither phenyl nor other radicals are transferred back from Ge to Si in the course of reactions of phenylgermanes with methylchlorosilanes in the presence of aluminum chloride; the only occurring processes are the exchange of the phenyl or methyl radicals bonded to Ge for the Cl atom bonded to Al and the disproportionation of phenylchlorogermanes.
