Zhun’, V. I. published the artcileReaction of Germanium Tetrachloride with Chloro(phenyl)silanes in the Presence of Aluminum Chloride, Recommanded Product: Difluorodiphenylsilane, the publication is Russian Journal of General Chemistry (2005), 75(6), 867-869, database is CAplus.
The effect of the quantity of AlCl3 on the direction and depth of reaction of GeCl4 with chloro(phenyl)silanes PhnSiCl4-n (n = 1-3) was studied to show that radical exchange between Ge and Si is initiated only if the mixture contains ¡Ý2.5-5% of AlCl3. With trichloro(phenyl)silane, the radical exchange is initiated at 5% of AlCl3 and results in exclusive formation of trichloro(phenyl)germane. The reactions of GeCl4 with dichlorodiphenylsilane and chlorotriphenylsilane in the presence = 2.5-7.5% of AlCl3 give dichlorodiphenylgermane as the major product, and at AlCl3 concentrations of >10% the major product becomes trichloro(phenyl)germane.
Russian Journal of General Chemistry published new progress about 312-40-3. 312-40-3 belongs to catalysis-chemistry, auxiliary class Organic Silicones, name is Difluorodiphenylsilane, and the molecular formula is C23H20BN, Recommanded Product: Difluorodiphenylsilane.
