Description General description 3-Bromothianaphthene is a heteroaryl halide. It undergoes Suzuki-Miyaura reaction with phenylboronic acid (PBA) or 3-thienylboronic acid in the presence of a novel heterogeneous Pd catalyst [Pd@PDEB, PDEB=poly(1,3-diethynylbenzene)]. The substitution reaction of 3-bromothianaphthene with piperidine to form 3-piperidinothianaphthene as the major product has been reported. Application 3-Bromothianaphthene may be used in the synthesis of (benzo[b]thiophen-3-yl)trimethylstannane. Packaging 5, 25 mL in glass bottle
