Description	The reaction of substituted benzenediazonium tetraphenylborates with the b-enaminones derived from pentane-2,4-dione, 1-phenylbutane-1,3-dione and 1,4-diphenylbutane-1,3-dione with primary or secondary (N-methyl, N-phenyl) amino group in CH2Cl2 gives 5-(subst.phenyldiazenyl)-2,2-diphenyl-4,6-disubstituted-, or 5-(subst.phenyldiazenyl)-2,2-diphenyl-3,4,6-trisubstituted-1,3,2lambda4-oxazaborines, respectively. The reaction intermediate of these compounds has been identified, and the mechanism of the reaction has been suggested. Substituted 1,3,2lambda4-oxazaborines gradually rearrange into 1,2,4,3lambda4-triazaborines at temperatures above 100 °C.
