City Chemical manufactures high purity Diethylsilane, CAS 542-91-6 in bulk quantity. Diethylsilane is a reagent used in the chemical vapor deposition (CVD) of SiO2 for microelectronics. It is also used as a precursor to develop (3-allylsulfanyl-propyl)-diethyl-silane by employing (Ph3P)3RhCl reagent. In addition, it can be used as a reductant in catalytic reduction of secondary amides to imines and secondary amines has been achieved using readily available iridium catalysts such as [Ir(COE)2Cl]2. This system requires low catalyst loading and shows high efficiency and an appreciable level of functional group tolerance. As a reduction agent, it also be used to convert polycarboxylic acids into their corresponding alkanes.
