Abstract

Catalytic properties of the camphor-derived complexes <i>trans</i>-[PdCl<sub>2</sub>(L1)<sub>2</sub>], R = Me<sub>2</sub>N (<strong>1</strong>), <i>i</i>-Pr (<strong>3</strong>), C<sub>6</sub>H<sub>5</sub> (<strong>4</strong>), in PhC≡CMe cyclotrimerization are highly dependent on the characteristics of the R group. Their activity decreases in the order <strong>1</strong> &gt; <strong>3</strong> &gt; <strong>4</strong>. The effects of geometric and/or electronic parameters on the catalytic activity of the complexes are evaluated on the basis of X-ray and electrochemical data. <p>
