Results are given to show that a volatile Si-N compound, SiH3NSiH23, other than trisilylamine can be isolated from the reaction of silyl chloride and NH3. The compound is thought to be N, N, N -trisilylcyclotrisilazane. The proton nuclear magnetic resonance spectra of C2H5I, CH3SiH3, and CH3SiH2I were obtained in CS2 solution with tetramethylsilane added as an internal standard. That of Si2H5I, disilanyl iodide, was observed in the neat state and with Me4Si and as a solution with CC14. Exchange reactions were observed between trisilylamine and trisilylamine-d sub 9 and trisilylamine and silyl chloride-d sub 3. The reaction of SiH33N and DC1 did not indicate that any H exchange occurred during the reaction. Reactions of nickel carbonyl with biphosphines and of PF3 with NiCO4 were also studied.
