Abstract
Silazane cpds are prepd by reacting a halosil are of formula R3SiX (where R is lower alkyl, vinyl, alkoxy or Ph; and X is halogen) and a dihalosilane of formula R2SiX2 with ammonia in the presence of alkalene diamine of formula R2'NR"NR2' (where R2' is H, lower alkyl or silyl radical -SiX3, where X is lower alkyl; and R" is a divalent alkylene radical of 2-4C) to form a liquid alkylene diamine-hydrogen halide salt phase which will settle to the bottom of the liq. silazane product phase which is also formed, while maintaining a sepn temp. of >=70 degrees C; the molar amt. of ammonia used is >=50% of the amt. which is stoichiometrically equivalent to the equiv. no. of silane-halogen bonds to be reacted, and the molar amt. of alkylene diamine is from 90% of the amt. that is stoichiometrically equiv. to the equiv. no. of silane-halogen bonds to be reacted to a stoichiometric excess of 10%. Prod. is useful in synthetic penicillins mfr.
