Organoboron compounds. XVII. Preparation and hydrolytic properties of some substituted borazines containing fluoreseent groups

Abstract

For the detection of neutrons by means of scintillation counters, compounds which have both high neutrón cross sections and are strongly fluoreseent are desirable. Interesting examples of such types of compounds can be obtained by introducing polyphenyl groups into the borazine molecule. Tn the present paper the preparation of four such compounds, B-tris(diphenylyl)-N-trimethylborazine (I), B-tris(diphenylyl)-N-triphenyl-borazine (II), B-tris(a-naphthyl)-N-trimethylborazine(III), and B-tris(p-terphenylyl)-N-trimethylborazine (IV), is described and their rates of hydrolysi are compared. The structural formulation of the compounds is given in Chart I.
