Abstract

Silicon tetrachloride and alkyl- and aryl-chlorosilanes are alkylated by reacting with aluminium alkyl compounds in the presence of alkali metal chlorides in amounts which are approximately equimolecular to that of the aluminium compounds. Suitable reaction temperatures are up to 500 DEG C. Solvents &c. may be employed. Specified aluminium alkyl compounds are aluminium trimethyl and triethyl as well as propyl and butyl, and aluminium methyl and ethyl chlorides. In the examples: (1) aluminium triethyl is heated in a pressure vessel at 300 DEG C. with silicon tetrachloride and sodium chloride to give a mixture of (Et)3SiCl, (Et)2SiCl2, EtSiCl3 and (Et)4Si, with a solid residue of NaAlCl4; (2) similar to (1), the product including minor amounts of compounds containing Si-O and Si-C-Si bonds; (3) (Et)2SiCl2 is reacted with Al(Et)3 to give a mixture of (Et)3SiCl and (Et)4Si; (4) as in (1), using mineral oil as diluent; (5) phenyltrichlorosilane is reacted with Al(Et)3 and NaCl in mineral oil to give a phenylethylchlorosilane mixture.
