Abstract
Considering the efficacy of platinum nanoparticles in various research areas, we report a new carbosphere-nanofabricated Pt–Si nanocomposite with a size of ca. 8 nm as measured using HRTEM and DLS. This nanocomposite was synthesized by an eco-friendly hydrothermal approach using an efficient and unprecedented in situ imination through oxidative C=C cleavage. Based on HRMS kinetic studies and control experiments, a plausible mechanistic approach was developed in which the olefin counterpart is converted into the corresponding aldehyde by exploiting Pt–Si mediated nanocatalysis. The major advantages of this work include the eco-friendly hydrothermal synthesis of the Pt–Si nanocomposite for the non-traditional imination from cinnamic acid or styrene derivatives with diverse amines through oxidative cleavage of the C=C bond. The method will find diverse applications in late-stage functionalizations.
