ALKYLENE OXIDE POLYMERIZATION USING PHOSPHONIUM CATALYSTS
Alkoxylation reactions are performed in the presence of a phosphonium catalyst having the structure P+(XR1R2R3)A1 wherein R1 is a group having an unsubstituted or inertly substituted aromatic five-member ring having a direct bond between an atom of the aromatic five-member ring and the phosphorus at...

description | Alkoxylation reactions are performed in the presence of a phosphonium catalyst having the structure P+(XR1R2R3)A1 wherein R1 is a group having an unsubstituted or inertly substituted aromatic five-member ring having a direct bond between an atom of the aromatic five-member ring and the phosphorus atom, and each R2 is independently a group having an unsubstituted or inertly substituted, optionally heteroatomic, aromatic five- or six-member ring having a direct bond between a carbon atom of the optionally heteroatomic aromatic five- or six-member ring and the phosphorus atom, X is selected from fluorine, chlorine, bromine, iodine, C1-12 perfluoroalkyl, C1-12 alkyl, aryloxy and C1-12 alkoxy, and A is a weakly coordinating anion.
L'invention concerne des réactions d'alcoxylation qui sont effectuées en présence d'un catalyseur de phosphonium ayant la structure P+(XR1R2R3)A1 dans laquelle R1 est un groupe ayant un cycle à cinq chaînons aromatique non substitué ou substitué de manière inerte ayant une liaison directe entre un atome du cycle à cinq chaînons aromatique et l'atome de phosphore, et chaque R2 est indépendamment un groupe ayant un cycle aromatique à cinq ou six chaînons, éventuellement hétéroatomique, substitué ou non substitué ayant une liaison directe entre un atome de carbone du cycle aromatique à cinq ou six chaînons éventuellement hétéroatomique et l'atome de phosphore, X est choisi parmi le fluor, le chlore, le brome, l'iode, le perfluoroalkyle en C1-12, l'alkyle en C1-12, l'aryloxy et l'alcoxy en C1-12 , et A est un anion faiblement coordonnant. |
