N2 - We investigated infrared multiphoton dissociation and isomerization reactions of 2,3-dihydrofuran (2,3-DHF), cyclopropanecaboxaldehyde (CPCA) and crotonaldehyde (CA) with free electron laser at Tokyo University of Science (FEL-TUS). From 2,3-DHF as a starting material, CPCA and CA were the main isomerization products. From the measured [CPCA]/[CA] ratio, the equivalent temperature for the vibrationally hot 2,3-DHF was estimated to be 1300-1500 K. From CPCA, both 2,3-DHF and CA were detected as isomerization products. No isomerization reaction from trans-CA to CPCA and 2,3-DHF was recognized and the dissociation to propylene was the dominant process. The experimentally identified reaction pathways are well explainable by quantum chemical calculations at the MP2/cc-pVDZ level.
