โœฆ Synopsis

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-membered furanone ring system have been the

Recently, it has been reported that the five-membered heterocyclic compounds containing two vicinal hetero-atoms interchanged their positions to 1,3-systems as a common mode of reaction when irradiated with ultraviolet light. Examples include the photo-induced rearrangement of indazoles to benzimid

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
