Rapidly connect the receiver with the silicochloroform via standard ground-glass joint 3 to an apparatus for fractional distillation under atmospheric pressure (see Fig. 20) and close side arm 4 (see Fig. Ill) with a glass stopper. Perform distillation and gather the fraction boiling at 34-37 °C. 

Carbon brings about reduction of arsenious oxide at a temperature below red heat,11 while in carbon monoxide reduction begins at 60° C.12 The numerous reactions of arsenious oxide with organic compounds are described in Vol. XI, Part II, of this Series. Silicon tetrachloride heated for 30 hours at 270° to 280° C. with the oxide yields arsenic trichloride,13 whilst silicochloroform when heated with the oxide in the presence of aqueous sodium hydroxide-or sodium hydrogen carbonate... 

Stable at room temperature but decomposes at approximately 400°C. Slowly decomposes in water practically insoluble in alcohol, ether, benzene, chloroform, silicochloroform, and silicon tetrachloride. Decomposes in potassium hydroxide solutions.1... 

Silicochloroform. SiHCL, trichlorosilane, so called by analogy to chloroform, CHCI3, trichloromethane. 

It is well established that silicochloroform is easily deprotonated by amines to give the highly nucleophilic anion SiClj" [8] (Eq. 2). 

Tetrapropylsilicane is obtained along with tripropylsilicane by the action of zinc propyl on silicochloroform (trichlorosilicane) at 120° to 150° C. The lower fraction is tripropylsilicane and the higher one tetrapropylsilicane. The reaction is probably represented thus ... 

Gas, repulsive odor. d, s (liq) 0.68. Solidifies at approx —200. mp —185 bp —112. Stable at ordinary temps completely dec at approx 400° into silicon and hydrogen dec by an electric discharge ignites in an atm of chlorine ignites in air by raising the temp. Slowly dec in water practically insol in ale, ether, benzene, chloroform, silicochloroform and silicon tetrachloride. Dec in potassium hydroxide solns. 

Trichlorosilane (SiHCls, silicochloroform) [10025-78-2] M 135.4, m -126°, b 31,8 /atm, 32-34 /atm, 36.5°/atm, d 1.342, n p 1.4020. This volatile trichlorosilane can be obtained from silane and HCl in the presence of AICI3, and is purified by fractional distillation at atmospheric pressure in the strict absence of moisture. However, S1HCI3 is best prepared by placing finely powdered silicon (purified by boiling with HCl... 

The preparation of a variety of higher polysilanes using silylmetallic reagents has been described (4, 5, 14). More recently, silylmetallics have been successfully employed in the synthesis of branched polysilanes. Treatment of silicochloroform with either triphenyl- or dimethylphenyl-silyllithium gives the corresponding tris derivatives.
