일반 설명

2-Bromo-5-chlorothiophene is a halogen-substituted thiophene and its photodissociation dynamics was studied by resonance enhanced multiphoton ionization time-of-flight technique. Electrochemical reduction of 2-bromo-5-chlorothiophene at carbon cathode in dimethylformamide containing tetramethylammonium perchlorate was reported.

애플리케이션

2-Bromo-5-chlorothiophene was used in the synthesis of monomer of 1,4-bis(5-chlorothiophene)-buta-1,3-diyne and 5-chloro-2-[(trimethylsilyl)-ethynyl]thiophene.

The photodissociation dynamics of halogen-substituted thiophenes, namely, 2-chlorothiophene and 2-bromo-5-chlorothiophene, has been studied in a supersonic molecular beam around 235 nm, using resonance enhanced multiphoton ionization (REMPI) time-of-flight (TOF) technique, by detecting the nascent state of the primary halogen atoms.

Cyclic voltammetry and controlled-potential electrolysis have been employed to probe the electrochemical reduction of a number of mono- and dihalothiophenes at carbon cathodes in dimethylformamide containing tetramethylammonium perchlorate. Reduction of 2-bromo-, 3-bromo-, 2-chloro-, 3-chloro-, and 2-iodothiophene gives rise to a
