Abstract: | Abstract The first examples of compounds R1R2GeSe2C6H4R3 (R1,R2=CH3 C2H5, C3H2, n-C4H9, i-C5H11, Ph, p-CH3Ph. R3=H, CH3, OCH3) were easily obtained (40–80% yield) from electrophilic cleavage of diselenophenylene zirconocenes by dialkyl or diaryl dichlorogermanes. The synthesis of a spirodi-selenagermole was achieved in the same way using germanium tetrachloride. Analytical data, 1H and 77Se NMR. mass spectra are perfectly consistent with the expected structures. |
