✦ Synopsis

2,5-Bis(dicyanomethylene)-2,5-dihydrofuran (TCNF) is not homopolymerizable with any initiators, but copolymerizable with styrene (St) in an alternating fashion. Reactivity of TCNF was compared with that of 2,5-bis(dicyanomethylene)-2,5dihydrothiophene (TCNT) on the basis of the terpolymerization of the TCNT-TCNF-St system and the rates of addition reactions of AIBN with TCNT and with TCNF. TCNF was found to be lower in reactivity than TCNT. The relative reactivity was explained with the energy difference between quinonoid structure and benzenoid one.

Direct irradiation of 5,5-diaryl-2,5\_dihydrofurans results in a di-r-methane rearrangement to give 3-penten-l-one derivatives. Triplet sensitization leads to the formation of a 2-oxabicyclo[2.l.O]pentane which is extremely sensitive to heat and oxygen. The light-induced transformations of the five
