Novel derivatives of hypervalent germanium: synthesis, structure, and stability†
Abstract
Syntheses of a series of novel germanium complexes, viz. RN(CH2CH2NC6F5)2GeHal2 (1, R = Me, Hal = Cl; 2, R = Me, Hal = Br; 3, R = PhCH2, Hal = Cl; 4, R = PhCH2, Hal = Br), as well as MeN[CH2(2-C4H3N)]2GeHal2 (5, Hal = Cl; 6, Hal = Br), by the reaction of GeHal4 with dilithium salts of corresponding (CH2CH2NSiMe3)2Ge
(Hal)]2 (12, Hal = Cl; 13, Hal = Br) were obtained by the reaction of GeHal4 with dilithium salt of Me3SiN(CH2CH2NHSiMe3)2 (14). DFT calculations on this reaction were carried out and discussed. Composition and structures of the novel compounds were established by elemental analyses, 1H, 13C, and
