- Аннотация: The reaction of (phenylacetylenyl)triethoxygermane, (EtO)(3)GeCdropCPh (3), with bromine in CHCl3/CCl4 solution leads to a mixture of Z- and E- (EtO)(3)GeC(Br)=C(Br)Ph (4) in the ratio Z/E = 3/1. Treatment of this product with N(CH2CH2OH)(3) affords a mixture of Z- and E-N(CH2CH2O)(3)GeC(Br)=C(Br)Ph (2) in high yield. Compound E-2 was isolated in 16% yield. The molecular composition and the structure of all new compounds have been established by elemental analyses, H-1 and C-13 NMR spectroscopy. The crystal structure of E-2 is reported. The possible reasons for the different Z/E ratios in the products of the bromination of 3 and N(CH2CH2O)(3)GeC=CPh (1) are discussed using DFT calculations.
