CATALYTIC PROCESS FOR MAKING COMPOUNDSHAVING A NON-LEWIS ACID/BASEGROUP IIIA METAL TO GROUP VA NONMETAL BONDAbstractA process for preparing tractable preceramicprecursors of Group IIIA metal/Group VA nonmetalcompounds, such as BN. in which a first reactantcontaining a Group VA nonmetal to hydrogen bond, such asammonia or an amine is reacted with a second reactantcontaining a Group IIIA metal to hydrogen bond, such asa metal hydride. in the presence of a metal catalystthat catalyzes dehydrocoupling of the bonds to form theprecursor. Further reaction of the precursor in thepresence of the catalyst forms oligomeric/polymericforms of the precursor.
