Polymer stabilized metal nanoparticles are of critical importance because their reactivity and assembly can be controlled by controlling the stabilizing polymer structures. In recent years, our work has been directed towards devising and developing new strategy to invent selective and recyclable nanosized catalysts. In this paper, we describe a one pot synthetic route and detailed characterization of Pt-polysiloxane nanoconjugates. In the view of their utility in catalysis, we also present anew approach to achieve their inter conversion from soluble (homogeneous) to insoluble (heterogeneous) and from insoluble (heterogeneous) to soluble (homogeneous) states. In addition, we present their applications as highly regioselective and recyclable hydrosilylation catalyst.
