Photochemical reactions of Thienyl-, Bithienyl-, Terthienyl- and Thienylaroyl-methanols

Krishnaswamy, N. R.,Kumar, Ch. Siva Sai Kamana,Prasanna, S.

, p. 1801 - 1830 (2007/10/02)

Photochemical reactions of some thienyl-, bithienyl-, terthienyl- and thienylaroyl-methanols were studied in the neat state as well as in solvents like methanol and benzene.The terthienylmethanols were found to be susceptible to photo-sensitized oxidation which was inhibited by singlet oxygen quenchers.The photoproducts were isolated, characterised by spectroscopic methods and in some cases by synthesis.
