Phosphazenium salt mixtures containing hexakis(amino)diphosphazenium, tetrakis(amino)-phosphonium and polyaminophosphazenium salts

摘要

The invention relates to mixtures containing 5 to 99.5 wt. % of a compound of formula (I), 95 to 0.5 wt. % of a compound of formula (II) and a maximum of 10 wt. % of one of several compounds of general formula (III a), wherein A¹-A³² which are independent from each other are equal or different and represent a straight-chained or branched alkyl or alkenyl having 1-12 carbon atoms, cycloalkyl having 48 carbon atoms, an aryl having 6-12 carbon atoms, an aralkyl having 7-12 carbon atoms, or A¹-A², A³-A⁴, A⁵-A⁶ etc. -A³¹-A³² which are independent from each other and are equal or different and are connected together directly or via O or N-A³³ to a ring having 3-7 ring members, A³³ represents an alkyl having 1-4 carbon atoms. X₁ and/or X₂ and/or X₃ which are independent from each other represent a radical of formula (III b), or the radical X1 and/or X₂ and/or X₃ as well as a straight-chained or branched alkyl or alkenyl having 1-12 carbon atoms, cycloalkyl having 4-8 carbon atoms represent an aryl having 6-12 carbon atoms, an aralkyl having 7-12 carbon atoms, or respectively the radicals which are disposed on an identically bound nitrogen atom, e.g. A¹ and A², A³ and A⁴, A⁵ and A⁶ etc. -A³¹ and A³² which are independent from each other are equal or different and are connected together directly or via O or N-A³³ to a ring having 3-7 ring members and A³³ represents an alkyl having 1-4 carbon atoms and B^- represents a single-valent organic or inorganic acid radical or the equivalent of a multi-valent acid radical. The mixtures can be used as catalysts and co-catalysts for phase transfer reactions, nucleophilic substitution reactions or halogen-fluoro-exchange reactions.
