Unorthodox Nanocatalysis through Carbosphere-Nanofabricated Pt-Si Nanocomposite: Effective Tandem Imination Protocol involving Oxidative C=C Cleavage

Considering the extensive efficacy of platinum nanoparticles in various research areas, we report a new carbosphere-nanofabricated Pt-Si nanocomposite (~8 nm) measured using HRTEM and DLS. This nanocomposite was synthesized by an eco-friendly hydrothermal approach for utilization in an efficient and unprecedented in situ imination through oxidative C=C cleavage. Utilizing HRMS Kinetic study and controlled experiments, plausible mechanistic approach predicts that the olefin counterpart is converted into corresponding aldehyde by exploiting Pt-Si mediated nanocatalysis. The major advantages of this work include the eco-friendly hydrothermal synthesis of the innovative Pt-Si nanocomposite for the non-traditional imination from cinnamic acid or styrene derivatives with diverse amines through oxidative cleavage of C=C bond which will find diverse application in late-stage functionalization.
