Convenient Synthesis of Unsymmetrically B-Substituted Borazines.

摘要

The reaction of (C2H5BNCH3)3 with one molar equivalent of BBr3 yields Borazine which was transformed into the derivatives (CH3S) (C2H5)2B3N3(CH3)3 by reaction with Pb(SCH3)2, and to (H2N)(C2H5)2B3N3(CH3)3 by reaction with anhydrous ammonia. The reaction of (C2H5BNCH3)3 with two molar equivalents of boron tribromide proceeds in similar fashion to yield Br2(C2H5)B3N3(CH3)3 burine, polymers.
