Very low pressure vapor phase pyrolysis (flash thermolysis) of four-membered ring compounds was followed by microwave spectroscopic detection of the reaction products.The molecules studied included substituted cyclobutanes, thietanes, oxetane and azetidine.Microwave spectroscopy is well suited not only to observe stable reaction products but also to detect unstable species formed during pyrolysis.The investigation provided a wealth of information on typical decomposition patterns during pyrolysis of four-membered ring compounds.In addition, new methods were found for producing some unstable molecules with improved efficiency.
