Poly(germanium thiolate): a new class of organometallic polymers having a germanium‐sulfur bond in the main chain

摘要

AbstractA novel germanium‐containing copolymer3 ahaving a germanium(IV) unit and a trimethylene sulfide unit alternatingly in the main chain was prepared by the combined use of a germylene, 1,3‐bis(trimethylsilyl)‐1,3‐diaza‐2‐germa(II)‐indan (1 a) and thietane (2). The resulting copolymer has a very high molecular weight (M̄w>106). The usage of a germylene, bisbis(trimethylsilyl)aminatogermanium(II) (1 b), as a comonomer also gave an alternating copolymer3 bwith high molecular weight in good yields. On the other hand, the reaction of a germylene, bis(N‐trimethylsilyl‐tert‐butylaminato)germanium(II) (c), with thietane afforded a 1 : 1 adduct4chaving a 1‐thia‐2‐germacyclopentane structure without producin
