Accessing π-expanded heterocyclics beyond dibenzothiophene: Syntheses and properties of phenanthrothiophenes

A series of phenanthrothiophenes are designed and synthesized from polyarylthiophenes through regioselective Scholl reactions in one step using iron chloride as catalyst. The molecular structures of these heteroarenes displayed multiple twisted fjords, which perturb the shapes of the polycyclic frameworks to pack in slipped to near-perfect face-to-face styles in parallel or antiparallel packings. Field-effect transistor devices using single crystals of 6,12-difluorodiphenanthro[9, 10-b:9′, 10′]thiophene gave a hole mobility of 0.22 cm2 V?1 s?1.

One-pot oxidation and bromination of 3,4-diaryl-2,5-dihydrothiophenes using Br2: Synthesis and application of 3,4-diaryl-2,5-dibromothiophenes

(Chemical Equation Presented) A class of 3,4-diaryl-2,5-dibromothiophenes (1b-5b) was synthesized by a one-pot reaction of 3,4-diaryl-2,5- dihydrothiophenes with Br2 reagent in excellent yield (83-92%). It was found that Br2 performed a double function (oxidation and bromination) during the conversion of 3,4-diaryl-2,5-dihydrothiophenes to 3,4-diaryl-2,5-dibromothiophenes. The application of 3,4-diaryl-2,5- dibromothiophenes used as building blocks was also investigated. Employing 3,4-diphenyl-2,5-dibromothiophene (1b) as a template, a class of 2,3,4,5-tetraarylthiophenes was prepared by the Suzuki coupling reaction. This provided a new and simple approach to the preparation of 2,3,4,5- tetraarylthiophenes.

NOVEL RING CONTRACTIONS OF 2,7-DIHYDRO-3,6-DIPHENYL-1,4,5-THIADIAZEPINE VIA A HALOGENATION-DEHALOGENATION PROCESS

2,7-Dihydro-3,6-diphenyl-1,4,5-thiadiazepine undergoes novel ring contractions via a halogenation-dehalogenation process in methanol, giving sulfur-containing five-membered cyclic compounds: this result is a great contrast to the ring contraction with ext
