ABSTRACT:
An optically-active or chiral compound is described which comprises
(A) at least one quaternary nitrogen or phosphorus cation provided that if the cation is a quaternary nitrogen cation containing a hydroxyalkyl group, the hydroxyalkyl group is free of chlorine, and
(B) at least one optically-active anion.
In one embodiment, the optically-active anion is an optically-active carboxylic acid anion. The process for preparing such optically-active compounds also is described and such compounds may be prepared by reacting
(A) at least one quaternary nitrogen or phosphorus salt with
(B) at least one optically-active reactant capable of reacting with the salt provided that if the salt is a quaternary nitrogen salt containing a hydroxyalkyl group, the hydroxyalkyl group is free of chlorine.
