title: Phase-Transfer Catalysis via a Proton Sponge: A Bifunctional Role for Biscyclopropenimine.
abstract: The use of a bis(diisopropylamino)cyclopropenimine-substituted bis-protonated proton sponge as a bifunctional phase-transfer catalyst is reported. Experimental studies and DFT calculations suggest it operates simultaneously as a hydrogen bond donor and a phase-transfer catalyst, facilitating the movement of charged intermediates from the interface to the organic phase via favorable partitioning of hydrophilic/hydrophobic surface areas, resulting in high catalytic activity.
