Abstract

Silazanes (some of which are novel) are made by reacting a compound of the formula <FORM:1086250/C3/1> wherein R is a linear saturated unsubstituted or substituted hydrocarbon radical, an unsaturated hydrocarbon radical, H, or a substituted or unsubstituted aromatic hydrocarbon radical; R1 is H or CH3; R1 and R2 (which may be the same or different) are defined as for R or are Cl or Br; n is an integer; n1 is 3 or 4; and the ratio of C:Si in these compounds is 0.5-13:1, with a halosilane of formula <FORM:1086250/C3/2> wherein R and R1 are as defined and X is Cl or Br. The novel silazanes produced have the formula <FORM:1086250/C3/3> wherein R and R1 are as defined, R1 is H or CH3, X is Cl or Br, and if R is CH3, R1 and X are not identical. The reaction may be carried out in the presence of Lewis or ansolve acids (this term is defined) as catalysts at 30-200 DEG C. Specific groups R are Me, Et, Pr, Bu, g -chloropropyl, vinyl, phenyl, tolyl, o- or p-chlorophenyl and p-nitrophenyl.
