Abstract

Herein, we report a metal-free synthetic methodology for the C-alkylation of acetophenones following a hydrogen borrowing-like pathway using the commercially available inorganic oxidant K2S2O8 in conjunction with KOtBu. This study articulates the potential of K2S2O8 in fast initiation of the oxidation of benzyl alcohols to develop an atom-economical, easy, and more efficient methodology for the C-alkylation of various acetophenones and synthesis of a variety of substituted quinolines. Experimental data from control experiments, literature and characterization of intermediates through spectroscopic techniques support the proposed plausible mechanism.
