Method of making aluminum-free neopentasilane
A method of making neopentasilane, the method comprising:contacting perchloroneopentasilane with a reductive effective amount of an alkali metal aluminum hydride in an alkylaluminum compound of formula RxAlCl3-x, where R is alkyl having from at least 5 carbon atoms, x is an integer from 1 to 3, and the alkylaluminum compound has a boiling point of at least 250° C., at conditions sufficient to reduce the perchloroneopentasilane, to form a reaction product mixture comprising neopentasilane, and separating the neopentasilane from the product mixture to form a neopentasilane isolate.
