Streszczenie

A matrix isolation study of structure and infrared spectra of o-guaiacol (o-methoxyphenol, GU) has been performed showing that the most stable conformer of the compound is present in argon and xenon matrices. Photochemical reactions of o-guaiacol were induced using UV-laser radiation and followed by the FTIR spectroscopy. Four photolysis pathways have been considered based on the positions of new bands appearing during irradiation of the matrices. It was concluded that the cleavage of the OH bond is an initial step of the reactions and a number of photoproducts have been identified originating from the subsequent ring opening and decarbonylation processes as well as the OCH3 bond cleavage. Among the photoproducts are cyclopetadienone and long-chain ketenes with conjugated/cumulated CO and CC bonds.
