Abstract
Generally disclosed are boron-based organic cations, a method for their manufacture, a method for their use in ionic liquids, and a method for their use as phase-transfer catalysts. More specifically, the boron-based organic cations have an charge of 1+, 2+, or 3+.
Claims16
A cation having the formula:
- wherein n is an integer that is greater than or equal to 1;
- wherein each A is a diazole or triazole that is independently selected from the group consisting of:
- wherein each R is bonded to at least one carbon atom or at least one nitrogen atom;
- wherein when an R is bonded to at least one carbon atom, each R is independently selected from the group consisting of a hydrogen atom, a nitrogen-containing heterocycle, a diazole heterocycle, a triazole heterocycle, an alkyl moiety, and a nitrogen-containing alkyl moiety;
- wherein when an R is bonded to at least one nitrogen atom, each R is independently selected from the group consisting of a hydrogen atom and an alkyl moiety;
- wherein at least two of the cation's exterior nitrogen atoms have alkyl moieties-bonded thereto;
- and
- wherein each z is independently selected and is an integer greater than or equal to 0.
