The ability of trichlorosilane to redistribute in the presence of tetraethylethylenediamine (TEEDA) and methylene chloride to form a complex comprising dichlorosilane and TEEDA was evaluated. All reactions were performed in a glass flask under a blanket of dry nitrogen. Trichlorosilane was distilled before use. TEEDA was dried by refluxing over CaH2 and then distilled. Dichloromethane was distilled from P2O5 just prior to use. The volumes of materials placed in the flask are provided in Table 1. Materials were added to the flask through a rubber septum by means of a syringe.
