Quantification of the Lewis Basicities and Nucleophilicities of 1,3,5-Tris(dialkylamino)benzenes

Equilibrium constants for the formation of Wheland complexes from 1,3,5-tris(dialkylamino)benzenes and benzhydrylium ions (Ar2CH+) have been determined photometrically in dichloromethane solution at 20 degrees C. The Lewis basicity of the ring carbons increases in the series trimorpholinobenzene

Automated summary

Equilibrium constants for the formation of Wheland complexes from 1,3,5-tris(dialkylamino)benzenes and benzhydrylium ions were determined using photometric method in dichloromethane solution at 20 degrees C. The Lewis basicity of the ring carbons was found to increase in this series.
