Usage

General Description

N,N-dimethylsilanamine is a chemical compound with the molecular formula C2H9NSi. It is a colorless, volatile liquid with a faint, amine-like odor. N,N-dimethylsilanamine is commonly used as a precursor for the synthesis of various organosilicon compounds, such as silanes and siloxanes, which have applications in the production of silicones, silicone rubber, and other silicon-based materials. It is also used as a reagent in organic synthesis and as a building block in the production of pharmaceuticals and agrochemicals. N,N-dimethylsilanamine is a flammable liquid and is incompatible with strong oxidizing agents. It should be handled with caution and stored in a cool, well-ventilated area away from heat, sparks, and open flames.

Kinetics of silylene insertion into N-H bonds and the mechanism and kinetics of the pyrolysis of dimethylsilylamine

Product and kinetic data on the copyrolysis of silane with ammonia and of silane with dimethylamine are reported. The main products of the SiH4/NH3 reaction are disilane and silylamine, and the main products of the SiH4/Me2NH reaction are Si2H6 and Me2NSiH3. The silylamine products are produced by SiH2 insertions into the N-H bonds of the amine reactants, and rate constants for this insertion lie in the k2 ～ 2 × 109 M-1 s-1 range, with no temperature dependence within the errors. Kinetic and product data on the pyrolysis of dimethysilylamine are also presented. Reactant loss followed reasonable first-order kinetics and produced rate constants consistent with Arrhenius parameters of log A(sec-1) = 12.64 ± 0.98 and E = 48.02 ± 3.1 kcal/mol. A mechanism of reaction, based on the kinds of silylene intermediate reactions expected, is presented. Comparisons of mechanistic expectations with the product data, however, indicate a more complex reaction system.
