Structural, spectral, and electrochemical investigations of para-tolyl-substituted oligogermanes

The synthesis of four new oligogermanes containing para-tolyl-substituents has been achieved via the hydrogermolysis reaction, including the digermane Tol3GeGePh3, the trigermanes Tol3GeGePh2GeTol3 and Tol3GeGeTol2GeTol3, and the tetragermane Tol3GeGePh2GePh2GeTol3 (Tol?=?p-CH3C6H4). These four oligogermanes have been structurally characterized and their structures have been compared with those of their per-phenyl-substituted analogs. The digermane Tol3GeGePh3 exhibits an unusually short Ge-Ge bond distance of 2.408(1)?A?. The four para-tolyl-substituted oligogermanes have also been characterized by UV/visible spectroscopy and cyclic voltammetry. The expected red shift in the absorbance maximum with increasing catenation was observed for this series of compounds. Their cyclic voltammograms each contain n?-?1 irreversible oxidation waves (n?=?the number of Ge atoms), which is atypical since oligogermanes generally exhibit only one irreversible oxidation wave regardless of the degree of catenation.

Heavy cyclopropene analogues R4SiGe2 and R4Ge3 (R = SiMetBu2) - New members of the cyclic digermenes family

1H-Siladigermirene R4SiGe2 (2a) and 1H-trigermirene R4Ge3 (2b) (R = SiMetBu2) with a Ge{double bond, long}Ge double bond were synthesized by the reaction of tetrachlorodigermane RGeCl2-GeCl2R with dilithiosilane R2SiLi2 and dilithiogermane R2GeLi2, respectively. The skeletal Ge{double bond, long}Ge double bond of 2a is trans-bent (51.0(2)°) with a bond distance of 2.2429(6) A?. The reaction of both 2a and 2b with CH2Cl2 resulted in the formation of unusual four-membered ring compounds 5a and 5b as a result of a ring expansion reaction. 1H-Trisilirene 7a and 3H-disilagermirene 7b with an Si{double bond, long}Si double bond also smoothly reacted with CH2Cl2 to yield the four-membered ring systems 8a and 8b, respectively.
