Synthesis of Trimethylstannyl Arylboronate Compounds by Sandmeyer-Type Transformations and Their Applications in Chemoselective Cross-Coupling Reactions

摘要

A synthetic method based on Sandmeyer-type reactions to access both tin- and boron-substituted arenes from nitroaniline derivatives is described. This transformation can be applied to the synthesis of a series of functionalized trimethylstannyl arylboronates. In addition, the chemoselective reaction of the Stille and Suzuki?Miyaura cross-coupling reactions is explored, and a series of m- and p-terphenyl derivatives have been synthesized by conducting consecutive one-pot Stille and Suzuki?Miyaura crosscoupling reactions.
