Synthesis, Structure, and Properties of Quinone Methides Incorporating Thiophene and Bithiophene Derivatives: New Overcrowded Extended Quinonoid π-Systems

The title compounds were synthesized through multiple Suzuki-Miyaura couplings followed by oxidation, and their structures and properties are described. They show large conformational changes and three color change upon electronic reduction.

3,4-Dibromothiophene from 2-Bromothiophene

3,4-Dibromothiophene can be obtained in a reasonable yield by treating the readily available 2-bromothiophene with a mixture of equimolar amounts of sodamide and potassium tert-butoxide in liquid ammonia.

Polyhalogenoaromatic Compounds. Part 41. Photochemical Dehalogenation and Arylation Reactions of Polyhalogenoaromatic and Polyhalogenoheteroaromatic Compounds

Photolysis of pentachloro- and pentabromo-pyridine in diethyl ether or methanol leads to loss of β-halogen.A product (9) derived from attack on diethyl ether was also identified. 4-Bromotetrachloropyridine also undergoes loss of bromine and tetrachloro-4-iodopyridine loses iodine exclusively.Photodehalogenation of some perhalogenothiophens, tetrachloropyrimidine, and hexachlorobenzene is also described.Photolysis of pentachloroiodobenzene, tetrachloroiodopyridines, and trichloro-5-iodothiophen in benzene gives the corresponding polychloroaryl- or polychloroheteroaryl-benzenes.Photolysis of tetrachloro-4-(phenylthio)pyridine (3) gives 1,3,4-trichlorobenzothienopyridine (6), and the analogous perchloro(phenylthio)pyridine (37) gives the corresponding perchlorobenzothienopyridine (61).The scope of this type of photocyclisation has been explored; starting materials investigated include various arylthiopolyhalogenopyridines, some arylamino- and aryloxy-tetrachloropyridines, and 4-anilinotrichloropyrimidine.
