Diethylsilane Chemical Properties, Uses, Production
Description
Diethylsilane is a reagent used in the chemical vapor deposition of SiO2 for microelectronics. It is also used as a precursor to prepare (3-allylsulfanyl-propyl)-diethyl-silane by using (Ph3P)3RhCl as reagent. It can also 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.
