RT info:eu-repo/semantics/article T1 A Practical, One-Pot Synthesis of Highly Substituted Thiophenes and Benzo[b]thiophenes from Bromoenynes and o-Alkynylbromobenzenes A1 Guilarte Moreno, Verónica A1 Fernández Rodríguez, Manuel A. A1 García García, Patricia A1 Hernando Santa Cruz, Elsa A1 Sanz Díez, Roberto K1 Química orgánica K1 Chemistry, Organic K1 Chemistry, Organic AB An efficient synthesis of thiophenes and benzo[b]thiophenes has been developed from easily available bromoenynes and o-alkynylbromobenzene derivatives. This novel one-pot procedure involves a Pd-catalyzed C–S bond formation using a hydrogen sulfide surrogate followed by a heterocyclization reaction. Moreover, in situ functionalization with selected electrophiles further expands the potential of this methodology to the preparation of the corresponding highly substituted sulfur heterocycles.
