摘要
Herein, we describe the synthesis and Stille cross-coupling reactions of 2-(tributylstannyl)- and 2,5-bis(trimethylstannyl)tellurophene. The reactions were most optimal when using aryl iodides as coupling partners, and a mixed catalyst system consisting of tetrakis(triphenylphosphine)palladium(0) and copper(I) iodide, together with cesium fluoride as additive, in N,N-dimethylformamide. This is the first reported synthesis and use of stannylated tellurophenes for cross-coupling reactions.
