Efficient separation of a trifluoromethyl substituted organocatalyst: just add water.
A practical, cost-saving tagging approach is developed which takes advantage of the hydrophobicity of trifluoromethyl groups, exemplified by the application and recovery of a CBS precatalyst using tuned aqueous-organic media with minimum 50% water content.
