Palladium-Catalyzed Regioselective C–S Bond Cleavage of Thiophenes
摘要:
Herein, a Pd-catalyzed reaction of simple and diverse bromothiophenes with alkynes via regioselective C-S bond activation is reported. This provides a new approach to prepare sulfur-based heterocycles and fulvenes.
A simple and efficient palladium-catalyzed three-component domino reaction of bromothiophenes with internal alkynes has been developed to produce benzo[b]thiophenes in moderate to good yields.
已开发出一种简单高效的溴噻吩与内部炔烃的钯催化三组分多米诺反应,以中等至良好的产率生产苯并[ b ]噻吩。
Solvent free, phosphine free Pd-catalyzed annulations of aryl bromides with diarylacetylenes
Palladium nanoparticles and sodium acetate catalyze the reaction of aryl bromide with diarylacetylene to produce annulated products in good yield. One equivalent of PEG-600 serves as the solvent. This procedure is compatible with a wide variety of functional groups.
