A composition comprising a mixture of aluminum containing Lewis acids, said mixture corresponding to. the formula: (Ar f 3A1)(A1Q1 3)y(-A1Q2-O-) z where Ar f is a fluorinated aromatic hydrocarbyl moiety of from 6 to 30 carbon atoms; Q1 is C1-20 alkyl; Q2 is C1-20 hydrocarbyl, optionally substituted with one or more groups which independently each occurrence are hydrocarbyloxy, hydrocarbylsiloxy, hydrocarbylsilylamino, di(hydrocarbylsilyl)amino, hydrocarbylamino, di(hydrocarbyl)amino, di(hydrocarbyl)phosphino, or hydrocarbylsulfido groups having from 1 to 20 atoms other than hydrogen, or, optionally, two or more Q2 groups may be covalently linked with each other to form one or more fused rings or ring systems; y is a number from 0 to 1.0; z is a number from 0.1 to 20; and the moieties (Ar f 3A1)(A1Q1 3)y may exist as discrete entities or dynamic exchange products.

L'invention concerne une composition renfermant un mélange d'aluminium qui contient des acides de Lewis, ce mélange correspondant à la formule: (Ar?f¿¿3?Al)(AlQ?1¿¿3?)¿y?(-AlQ?2¿-O-)¿z?, dans laquelle Ar?f¿ représente un fragment hydrocarbyle aromatique fluoré avec 6 à 30 atomes de carbone; Q?1¿ désigne alkyle C¿1-20?; Q?2¿ symbolise hydrocarbyle C¿1-20?, éventuellement substitué avec un ou plusieurs groupes qui représentent indépendamment des groupes hydrocarbyloxy, hydrocarbylsiloxy, hydrocarbylsilylamino, di(hydrocarbylsilyl)amino, hydrocarbylamino, di(hydrocarbyl)amino, di(hydrocarbyl)phosphino, ou hydrocarbylsufido, ces groupes présentant 1 à 20 atomes autre qu'hydrogène, ou deux groupes Q?2¿ ou plus qui peuvent éventuellement être liés l'un à l'autre par covalence de manière à former un ou plusieurs cycles condensés ou systèmes cycliques; y est un chiffre variant entre 0 et 1,0; z désigne un chiffre situé entre 0,1 et 20; et les fragments (Ar?f¿¿3?Al)(AlQ?1¿¿3?)¿y? peuvent exister comme entités distinctes ou produits d'échange dynamique.
