Popis:	Three o- (dialkylaminomethyl)-benzeneboronic anhydrides are shown to be trimeric. Hydration of the corresponding anhydrides, which do not form complexes with pyridine, provides o-(N-morpholinomethyl)- and o-(dicyclohexylaminomethyl)- benzeneboronic acids. The latter acid shows remarkable stability to acid- catalyzed deboronation as well as dehydration. A new tetracyclic boron- containing heterocycle is reported. The structure of the compound, an o- methylene-bridged dinydrobenzoboradiazole, and some of its properties are discussed. (auth)
