Abstract

Irradiation of 3,4-dibromo-, 3,4-dichloro- and 3-chloro-2,5-dimethylthiophene 1,1-dioxide in the presence of pentacarbonyliron caused successive reductive dehalogenation of the substrates, and π-complexation of the parent compounds and of the reduced products to tricarbonyliron. A mechanism for the dehalogenation is suggested. The mass spectral fragmentation patterns of the thiophene dioxides and of the complexes are discussed.
