Synthesis of the First Benzodiselenagermoles and One Spirobisdiselenagermole

Abstract

The first examples of compounds R1R2GeSe,C,H,RZ (R1,R2 = CH,,' C2H,, C3H7, n-C,H,,, i-CsH,l, Ph, p-CH,Ph. RZ = H. CH,, OCH,) were easily obtained (40-80% yield) from electrophilic.cleavage of diselenophenylene zirconocenes by dialkyl or diaryl dichlorogermanes. The synthesis of a spirodiselenagermole was achieved in the same way using germanium tetrachloride. Analytical data, 'H and 77Se NMR. mass spectra are perfectly consistent with the expected structures.

Benzodiselenagermoles and spirobisbenzodiselenagermoles

“…Our early work in this area was the synthesis of the first examples of benzodiselenagermoles and spirobisbenzodiselenagermoles published recently as a preliminary report [28]. The present article discusses the synthesis and properties of the large new family of title compounds, either substituted or not in the benzene ring.…”
