reactions have been well-known, Pd(II) insertion into C-H bonds promoted by coordination of an oxygen-only group to the palladium remains rather rare. In the present study, the first cyclopalladation complex formed from a simple phenol ester was characterized by X-ray crystallography. A promising protocol for the ortho C-H activation/aryl-aryl coupling of phenol esters that was not sensitive to moisture
尽管含氮基团导向的环钯化反应已广为人知,但通过仅含氧的基团与钯的配位促进 Pd(II) 插入 CH 键的情况仍然相当罕见。在本研究中,第一个由简单苯酚酯形成的环钯化配合物通过 X 射线晶体学表征。然后建立了对水分或空气不敏感的苯酚酯邻位 CH 活化/芳基-芳基偶联的有前途的方案。该反应的效用已被证明可用于合成有用的苯酚衍生物。

Cathodic reduction of α, α′-dibromo-1,2-dialkylbenzenes in DMF containing Et4N+ Br− as supporting electrolyte, in the presence of dienophiles (e.g. maleic anhydride derivatives), yielded Diels-Alder adducts of o-quinodimethanes. Selective reduction of the benzylic dibromides was often possible even when their irreversible cyclic voltammetric reduction peak potentials were more negative than the Eo
