Provided herein are cinchonium betaine catalysts and methods of promoting asymmetric imine isomerization reactions using the same.

A process, apparatus, and cyclopropenimine (CPI) material for generating metal carbonates are disclosed. Generating the metal carbonates comprises reacting carbon dioxide (CO.sub.2) with CPI. Generating the metal carbonates also comprises forming a reaction mixture comprising water, metal cations, and a product of the reacting.
