Advances in Siloxane-Based Coupling Reactions: Novel 16-Electron Palladium(0) Tri-alkene Catalysts for Allyl-Aryl Coupling in Precursors to Amaryllidaceae Alkaloids

Polymerization of Diazoacetates Initiated by the Pd(N-arylmaleimide)/NaBPh4 System: Maleimide Insertion into a Pd–C Bond Preceding to Initiation Leading to Efficient α-Chain-End Functionalization of Poly(alkoxycarbonylmethylene)s

“…To the best of our knowledge, these three complexes obtained here are new Pd(0) complexes. Importantly, these complexes are bench-stable in sharp contrast to the previously reported Pd(0) complex with a similar structure, Pd­(PhMI)­(nbd), bearing one PhMI and one nbd as ligands, which was reported to be highly unstable at ambient temperature in a previous study . For example, 3 was stable at ambient temperature for at least one month under a N 2 atmosphere and able to be handled without use of a glovebox.…”

The remarkable stability of these easily prepared complexes would render them useful reagents for various applications utilizing the properties of Pd(0) complexes.…”
