Polythiophene‐functionalized magnetic carbon nanotube-supported copper(I) complex: a novel and retrievable heterogeneous catalyst for the “Phosphine- and Palladium-Free” Suzuki–Miyaura cross-coupling reaction

A simple preparation of catalysts with high catalytic activity and superior cycling stability is very desirable. In this contribution, magnetic carbon nanotube functionalized by polythiophene (CNT–Fe3O4–PTh) acts as an efficient and retrievable host for copper nanoparticles to prepare CNT–Fe3O4–PTh–Cu(I) as a nontoxic and inexpensive catalyst. FT-IR, TGA, EDX, VSM, XRD, FE-SEM, TEM, and AAS techniques were employed to characterize the structure...
