- Reaction of Hexachlorodisilane with Trichloroethynylsilane and 2-Propynyl Chloride in the Gas Phase
-
Reaction of acetylenic compounds (trichloroethynylsilane and 2-propynyl chloride) with hexachlorodisilane in the gas phase at 450-520°C was studied. Main products of the reaction were identified, and a mechanism of their formation was proposed. It was shown that of the two reaction centers of 2-propynyl chloride (C=≡C and C-Cl) only the C-Cl bond is involved in reaction with dichlorosilylenes generated from hexachlorodisilane.

- Gas-Phase Reactions of Hexachlorodisilane with Vinyl Chloride and Allyl Chloride
-
Gas-phase reactions of hexachlorodisilane with vinyl chloride and allyl chloride is studied. Dichlorosilylene generated from Si2Cl6 reacts with the above chloroalkenes mainly at the C-Cl bond to form alkenyltrichlorosilanes. The yields of vinyltrichlorosilane and allyltrichlorosilane are 45-63 and 49-81%, respectively. A mechanism of the reactions of Si2Cl6 with vinyl chloride and allyl chloride is proposed.

- Gas-phase reactions of hexachlorodisilane with chloroform, carbon tetrachloride, and Di- and tetrachloroethylenes
-
Gas-phase reactions of hexachlorodisilane with chloroalkanes (CHCl3 and CCl4) and chloroalkenes (ClCH=CHCl and Cl2C=CCl2) are studied. Dichlorosilylenes generated from Si2Cl6 insert into the C-Cl bonds in chloroalkanes; with chloroalkenes, insertion into the C-Cl bonds occurs along with cyclo-addition to the C=C bonds.

- PALLADIUM COMPLEXES IN THE HYDROSILYLATION OF ACETYLENE
-
The catalytic activities of triphenylphosphine-, trialkylphosphine-, and acetylacetone-palladium complexes in the hydrosilylation of acetylene with trichloro-, alkyldichloro-, triethyl, and triethoxy-silanes were investigated.The yields of the corresponding (triorganylsilyl)ethylenes and 1,2-bis(triorganylsilyl)ethanes (conditions: 70-80 deg C, solvent xylene) depend on the nature of the ligands on the palladium atom and the character of the substituents on the silicon atom in the hydride silane.
