Abstract

En 中文

Stable cyclopalladated complexes containing an (sp(3))C-Pd bond were synthesized via alpha-CH2 deprotonation and palladation of N-alkyl groups of carbene ligands bearing electron-withdrawing substituents. The strong electron donating strengths of the resulting C-NHC<^>C-sp3 chelators were experimentally identified, and the palladacycle underwent template-directed, versatile C-halogenation with X-2.
