The method of laser-induced chemical deposition of metal from solution was applied in the continuous in situ laser generation of metal copper catalysts for model organic synthesis reactions. The gas phase products producing during laser-induced copper deposition were analyzed by gas mass spectroscopy whereas solutions used for the copper deposition were investigated before and after laser irradiation using chromato-mass and NMR spectroscopy. It was found out that the catalysis of the studied organic reactions by metal catalysts generated during laser deposition process occurs only upon laser irradiation of the reaction mixture, in turn, the copper structures deposited under laser light exhibit no catalytic activity.
