Abstract
Reaction of N(CH 2CHRO) 3GeBr ( 2a, b) with LiCCPh affords N(CH 2CHRO) 3GeCCPh ( 1a, b) ( a, R=H; b, R=Me). Compound ( 1b) was also obtained by treatment of Cl 3GeCCPh ( 3) with N(CH 2CHMeOSnEt 3) 3 ( 4). ( 1a) reacts with N-bromosuccinimide to yield N(CH 2CH 2O) 3GeC(Br) 2C(O)Ph ( 5). Cis-N(CH 2CH 2O) 3GeC(Br)C(Br)Ph ( 6) is formed by the reaction of 1a with Br 2 in equivalent amounts. All compounds were characterized by 1H- and 13C-NMR spectroscopy and mass spectrometry. Single crystal structures of 1a and 6 were determined by X-ray diffraction studies.
