Abstract[English]
Provided are dual-task borinane-based catalysts comprising a compound of Formula I (I) wherein Y is an alkyl, aryl, cycloalkyl, or cycloaryl spacer; Z is a nitrogen or phosphorous atom; R is an alkyl, aryl, cycloalkyl, or cycloaryl group, or a polymeric support; and a, b, and c are integers independently selected from the group consisting of 0-100, methods of making the catalyst using a monocyclic borinane. Methods of using the catalysts include producing polyethers, polycarbonates, polyesters, and polyurethanes, and obtaining primary hydroxyl-derivatives of the polyethers and polycarbonates.[French]
L'invention concerne des catalyseurs à base de borinane à double tâche comprenant un composé de formule I (I) dans laquelle Y est un espaceur de type alkyle, aryle, cycloalkyle ou cycloaryle ; Z est un atome d'azote ou de phosphore ; R est un groupe alkyle, aryle, cycloalkyle ou cycloaryle, ou un support polymère ; et a, b et c sont des nombres entiers indépendamment choisis dans le groupe constitué par les nombres de 0 à 100, des procédés de fabrication du catalyseur à l'aide d'un borinane monocyclique. Des procédés d'utilisation des catalyseurs comprennent la production de polyéthers, de polycarbonates, de polyesters et de polyuréthanes, et l'obtention de dérivés hydroxyle primaires des polyéthers et polycarbonates.
