Evaluation of the synthesis of polysilanes by the reductive-coupling of dihaloorganosilanes

Hydrogermolysis reactions involving the α-germylated nitriles R3GeCH2CN (R=Ph, Pri, But) and germanium amides R3GeNMe2 (R=Pri, But) with Ph3GeH: Substituent-dependent reactivity and crystal structures of Pri3GeGePh3 and But3Ge[NHC(CH3)CHCN]

“…Well-developed methods for the preparation of silicon- [1][2][3][4][5][6][7][8][9][10][11] and tin- [12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28] containing oligomers and polymers have been known for some time. In the case of germanium, until recently existing methods for the synthesis of oligomeric systems have been complicated by low yields and/or the formation of mixtures of products .…”

“…Furthermore, the synthesis of Bu t 3 GeGePh 3 could not be achieved using neither the a-germylated nitrile Bu t 3 GeCH 2 CN nor the amide Bu t 3 GeNMe 2 . However, the latter reaction unexpectedly yielded the 3-amidocrotononitrile species Bu t 3 Ge[NHC(CH 3 )CHCN] which was isolated and structurally characterized. These findings are the focus of this paper.…”

Simulation of polysilane and polysilyne formation and structure

“…The Wurtz-type polymerization of dichlorodialkylsilanes and trichloroalkylsilanes is a complex process [2][3][4]. The polymerization proceeds by a chain growth process at the alkali metal surface, which plays an essential role in the formation of polymers of high molecular weight.…”

Low-energy synthesis of air-stable alkali metal colloids in a polymer/alkali halide matrix

“…Our characterisation of alkali metal colloids formed in the Wurtz synthesis of polysilanes has led to a more complete understanding of the reaction mechanism [9,20]. Polymer growth at the alkali metal/solvent interface consumes the metal.…”
