“…The structures of 3a , 5 , and 8 have been determined by a X-ray study. The main feature is the lenghtening of the Ge−CR 2 and Ge−O bonds due to the large steric congestion: 1.997−2.0227 and 1.819−1.863 Å, respectively (standard Ge−C and Ge−O bond lengths lie generally in the ranges 1.94−1.98 and 1.73−1.79 Å, respectively) 8a. In the six-membered ring of oxagermacyclohexene 3a (Figure ), the five atoms Ge, O(1), C(1), C(2), and C(3) are approximately in a plane; the mean deviation in relation to this mean plane is 0.05 Å, and the maximum deviation is 0.08 Å for O(1).…”

Dimesitylfluorenylidenegermane, Mes 2 GedCR 2 (1; Mes ) 2,4,6-trimethylphenyl, CR 2 ) fluorenylidene), undergoes a [2 + 4] cycloaddition with the CdCCdO system of R-ethylenic esters such as methyl acrylate, dimethyl maleate and dimethyl fumarate, and diethyl fumarate, leading to the 1,2-oxagerma-5-cyclohexenes 2 and 3a,b, respectively. With diethyl oxalate, maleic anhydride, and cyclopent-2-ene-1,3-dione [2 + 2] cycloadditions are observed between the GedC double bond and the carbonyl function, with formation of 1,2-oxagermetanes 4-6, respectively. In the last case, a double [2 + 2] cycloaddition on both CO groups to form a tricyclic compound occurs with excess germene. Germene 1 reacts exclusively by an ene reaction with 2-methyl-1,3-pentadione to give the corresponding (germyloxy)cyclopentenone 8.

This article provides an overview of the organometallic chemistry from 1994 to 2004. Major advances in the formation and breaking of GeC bonds are discussed, as are advances in the physical characterization of these compounds. Recent advances in the formation of organogermanium species containing multiple bonds to germanium and the formation of germanium‐centered radicals and cations are delineated. Applications to the synthesis of germanium‐containing polymers are overviewed.
