Synthese, Eigenschaften und Struktur einiger Silyl-Ethene/Synthesis, Properties, and Structure of Some Silyl-Ethenes

Abstract

Abstract trans-1,2-Dichloro-1,2-bis(trichlorosilyl)ethene (1) was prepared from Cl3CSiCl3 and copper powder, and its structure determined by single crystal X-ray diffraction (monoclinic, space group P21/n, a = 7.297(1), b = 10.964(1), c = 7.988(1) Å, β = 108.06(1)°; R = 0.037, Rw = 0.066). Cl3SiC=CSiCl3 , 2, forms a cobalt cage cluster on reaction with Co2(CO)8 formulated as (CO)6Co2C2(SiCl3)2 . Hydrosilylation with HSiCl3 gives tris(trichlorosilyl)ethene. -Bis(trimethylsilyl)ethine adds HSiCl3 to form 1-trichlorosilyl-1,2-bis(trimethylsilyl)ethene, which can be converted into the hydride with i-BU2AlH. All compounds are model systems for CVD production of amorphous silicon a-Si:C.
