The photochemical reaction of halofuran and halothiophene derivatives with alpha-methylstyrene shows that the presence of the methyl group can change the previously described reactivity of the substrate giving a mixture of two compounds. Furthermore, the use of heteroaryl allylic acetates causes a change in the regioselectivity of the photochemical reaction to yield the coupling products on the heterocyclic ring.
PHOTOCHEMICAL REACTIVITY OF HALOFURAN AND HALOTHIOPHENE DERIVATIVES IN THE PRESENCE OF ALPHA-METHYLSTYRENE AND HETEROARYL ALLYLIC ACETATES
1993
Abstract
The photochemical reaction of halofuran and halothiophene derivatives with alpha-methylstyrene shows that the presence of the methyl group can change the previously described reactivity of the substrate giving a mixture of two compounds. Furthermore, the use of heteroaryl allylic acetates causes a change in the regioselectivity of the photochemical reaction to yield the coupling products on the heterocyclic ring.File in questo prodotto:
