AZABOROXINE COMPOUNDS |
摘要 |
Azaboroxines of formula (I) wherein R and R', which may be the same or different, each represents an alkyl, an aryl, a cycloalkyl or heterocyclic group which may be unsubstituted or substituted with a least one halogen atom, R possibly also representing a silyl group and R' a silyloxy group, and X represents an oxygen atom or a sulphur atom. Polymeric azaboroxines having a repeating unit of (II) wherein R and R' have the same significance as above are based on such monomers. The monomers are prepared by reacting a suitable boroxine with a monofunctional isocyanate or thioisocyanate and the polymers by reacting the boroxine with a polyfunctional isocyanate or thioisocyanate. |
