D’Agostini, Agnese; D’Auria, Maurizio published the artcile< Photochemical coupling between halogenoheterocyclic and heterocyclic derivatives>, COA of Formula: C6H5IO2S, the main research area is photochem coupling aryl aryl haloheterocycle heterocycle; iodothiophene iodofuran photochem coupling acetoxyallylthiophene acetoxyallylfuran.
The photochem. reaction between 5-iodo-heteroaryl derivatives I (X = O, R = H; X = S, R = Me, H, OMe) and both 3-heteroaryl allylic alcs. II (Y = O, S, R1 = H) and acetates II (Y = O, S, R1 = Ac) have been investigated. The presence of an alc. function was not compatible with photochem. coupling since compounds I were photoreduced in the presence of an alc. In contrast, the acetates gave the expected coupling products III (same X, Y, R, mixture of E and Z isomers). The presence of a weak electron-withdrawing group on the alkene induced an inverted regiochem. giving only aryl-aryl coupling products. The same behavior was observed using 2-(3-acetoxyprop-1-ynyl)thiophene, in which case only the product derived from aryl-aryl coupling was again observed When 2-prop-1-ynylthiophene was used as starting material, the product resulting from attack on the Me group was also observed Photochem. coupling between 2-thienylacetonitrile and halothienyl derivatives I (X = S, R = Me, H) gave no reaction product. In contrast, the irradiation of Me 2-thienylacetate and Me 2-(2-thienyl)propionate in the presence of I (X = S, R = Me, H) did give the corresponding aryl-aryl coupling products.
