N-[(Chlorodimethylgermyl)methyl]lactams and -amides containing a five-coordinate germanium atom react with Grignard reagents chemoselectively by the Ge-Cl bond to form four-coordinate germanium compounds. The method of competitive reactions was used to es

Photochemical reactions of vinyl-, styryl- and benzyl-substituted digermanes by chemical trapping experiments.Photolysis of vinylpentamethyldigermane afforded 1-trimethyl-2-(pentamethyldigermyl)ethane as a major product, and styrylpentamethyldigermanes gave mainly styryltrimethylgermane.On the other hand, photolysis of benzyl-substituted digermanes (benzylpentamethyldigermane and 1,2-dibenzyltetramethyldigermane) gave hydrogermanes and hydrodigermanes as main products, respectively.These products were derived from germyl radicals generated by photoinduced homolysis of the germanium-germanium bond.In carbon tetra chloride (CCl4), these germyl radicals were converted to the corresponding chlorogermanes by abstraction of a chlorine atom.Germylene species were also to be evolved from such photolyses.
1,n-TRIORGANOSILYL MIGRATIONS IN THE REARRANGEMENTS OF SILYL-SUBSTITUTED ORGANOLITHIUM COMPOUNDS

Under the agency of the potent lithiating agent, n-butyllithium in TMEDA, an array of organosilanes was found to undergo 1,n-silyl rearangements via carbanionic intermediates.Unambiguous 1,2-, 1,3- and 1,4-silyl shifts were unconvered in 1-trimethylsilyl-
