Boronic acids which quickly deboronate under basic conditions, such as polyfluorophenylboronic acid and fivemembered 2-heteroaromatic boronic acids, are especially challenging coupling partners for Suzuki-Miyaura reactions. Nevertheless, being able to use these substrates is highly desirable for a n

## Abstract Polyfluorophenylboronic acid and five‐membered heteroaromatic boronic acids are used as coupling partners for Suzuki—Miyaura reactions in the presence of a newly developed precatalyst.
## Abstract magnified image The synthesis of 2‐acetyl‐6‐(1‐naphthyl)‐pyridine oxime ligand from 2,6‐dibromopyridine and 1‐bromo‐naphthalene is described, and the new palladium(II) complex used as a Pd(0) precatalyst in the Suzuki cross‐coupling reaction was studied. The results showed that the nov
