Zusammenfassung:	Novel compounds have the structure P+XR3B(PhF6)4 wherein the R groups are identical, each R being selected from phenyl, C1-12 alkoxyl-substituted phenyl or aryloxy-substituted phenyl, X is selected from chlorine, bromine, iodine and C1-12 alkoxy. The compounds are highly effective catalysts for a variety of reactions, including Friedel-Crafts reactions, hydrodeoxygenation reactions, dehydrocoupling of silanes with phenol and hydrodefluorination reactions. The compounds have been found to be particularly active alkoxylation catalysts. De nouveaux composés ont la structure P+XR3B(PhF6)4 dans laquelle les groupes R sont identiques, chaque R étant choisi parmi phényle, phényle en C1-12 substitué par alcoxyle ou phényle substitué par aryloxy, X est choisi parmi le chlore, le brome, l'iode et alcoky en C1-12. Les composés sont des catalyseurs hautement efficaces pour diverses réactions, y compris des réactions de Friedel-Crafts, des réactions d'hydrodésoxygénation, un déshydrocouplage de silanes avec des réactions de phénol et d'hydrodéfluoration. On a découvert que les composés sont des catalyseurs d'alcoxylation particulièrement actifs.
