Abstract: A newer catalyst was investigated as a catalyst for oxidative coupling of coumarin with propenyl phenols and alkene substrates. This resulted in dimerization of the two through C-O-C linkage yielding some novel coumarinolignanoids. These were characterized by elemental analysis, FT-IR, 1H NMR spectral studies. The rate of reaction was enhanced significantly there by decreasing the overall time of reaction and good product yield was also obtained.
