Tetraarylstannagermene: A molecule with a Ge=Sn double bond

A study was conducted on a molecule with a Ge=Sn double bond. The treatment of R2Ge=SnR2 with dry oxygen yielded a 3,4-germastannadioxetane with a stretched O-O bond length. It was found that the four-membered heterocyclic ring was folded from the torsion angle Ge-O-O-Sn of 31.4°.

Azadigermiridines by addition of diazomethane or trimethylsilyldiazomethane to a digermene

Tetrakis(2,4,6-triisopropylphenyl)digermene (2), prepared by treatment of germanium bis(trimethylsilyl)amide with 2,4,6-triisopropylphenyllithium, reacts with diazomethane or trimethylsilyldiazomethane in a [2+1] fashion to furnish the N-methyleneamino-substituted azadigermiridines 7 and 8, respectively. The dissociation equilibrium between 2 and bis(triisopropylphenyl)germylene has been confirmed by the trapping reaction with a 1,2-quinone, from which the 1,3-dioxa-2-germaindan 10 was isolated. The structures of 2, 7, 8, and 10 were determined by X-ray crystallography. The sterically congested digermene 2 has a short Ge-Ge double-bond length of 2.213(1) A.

Electronic absorption spectra of diorganogermylenes in matrices: Formation of diorganogermylene complexes with heteroatom-containing substrates

Diorganogermylenes were generated in hydrocarbon matrices at 77 K by the photolysis of 7-germanorbornadienes 1a-e or bis(trimethylsilyl)germanes 2a-g. The germylenes show electronic absorption bands at 420-558 nm. The germylenes react with heteroatom-containing substrates (R2O, R2S, R3P, R3N, RCl, and ROH) to form adducts, which show characteristic absorption bands at shorter wavelengths than those of germylenes.

Spectroscopic characterization of diarylgermylene complexes with heteroatom-containing substrates

Characteristic UV absorption bands of diarylgermylene complexes were observed in the reaction of diarylgermylenes with heteroatom-containing substrates in 3-MP/IP matrix at 77 K.
