Platinum–(phosphinito–phosphinous acid) complexes as bi-talented catalysts for oxidative fragmentation of piperidinols: an entry to primary amines

Platinum–(phosphinito–phosphinous acid) complex catalyzes the oxidative fragmentation of hindered piperidinols according to a hydrogen transfer induced methodology. This catalyst acts successively as both a hydrogen carrier and soft Lewis acid in a one pot – two steps process. This method can be applied to the synthesis of a wide variety of primary amines in a pure form by a simple acid–base extraction without further purification.
