Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>The combination of a new bifunctional phosphine and an acrylate generate a zwitterion in situ and it serves as an efficient catalyst for asymmetric reactions through a homogeneous ion‐pairing mode. This new catalytic system has been successfully applied to Mannich‐type reactions to give excellent results and it demonstrates a broad substrate scope. Such reactivity is not accessible with general organophosphine catalytic modes. Preliminary investigations into the mechanism are also presented.</p> </abstract>
