Abstract

Graphical abstract: Highlights: Synthesis of structurally distinctive tetraarylphosphonium inner-salts (TAPIS). TAPIS backbone could act as a Lewis base catalytic moiety. TAPIS could act as phase tag to facilitate recycling and reuse of the catalyst. Abstract: Tetraarylphosphonium inner-salts (TAPIS) have been designed, synthesized and verified as recyclable and reusable Lewis base catalysts. The resulted TAPIS catalyst has been successfully applied in Michael addition, cyanation and trifluoromethylation reactions.
