Untersuchungen von Diiodogermylen 和 Triphenylphosphindiiodogermylen 和 die Kristallstruktur von Triphenylphosphindiiodogermylen
摘要:
Reaktivitaten und chemische Eigenschaften von Diiodogermylen und Triphenylphosphindiiodogermylen wurden durch ihre Reaktionen mit Organolithium-Verbindungen oder Butadienen untersucht。Die Kristallstruktur von Triphenylphosphindiiodogermylen wurde rontgenographisch aufgeklart。
mixture of an organosilicon or organogermanium dihalide and 1,4-dibromo-2,3-bis(bromomethyl)-2-butene with an alkali metal forming hexahydrodimetallapentalenes, best yields were obtained by using lithium in ether/tetrahydrofuran. This reaction, when extended to 1,2-dichloro-disilanes and -digermanes gave the corresponding tetrametallaoctahydronaphthalenes. When activated zinc was used instead of alkali

substituted compounds exhibit a degenerate equilibrium which involves a planar germacyclopent-3-ene transition state. Reaction of 1-halogeno-1-(transition metal carbonyl)-substituted germacyclopent-3-enes with different transition metal carbonylate anions results in formation of mixed-metal carbonyl derivatives and reduction with LiAlH4 results in formation of a germanium hydride. Thermolysis of 5 results
