Pd(η3-1-PhC3H4)(η5-C5H5), an Unusually Effective Catalyst Precursor for Suzuki–Miyaura Cross-Coupling Reactions Catalyzed by Bis-Phosphine Palladium(0) Compounds

Asymmetric construction of quaternary α-nitro amides by palladium-catalyzed C(sp3)–H arylation

A Pd-catalyzed enantioselective C(sp³)–H arylation of N-(o-Br-aryl) anilides has been disclosed for the preparation of optically active quaternary amino acid derivatives. Quaternary α-nitro amides are constructed with stereoselectivities of up to 98% ee.

Synthesis of zwitterionic palladium complexes and their application as catalysts in cross-coupling reactions of aryl, heteroaryl and benzyl bromides with organoboron reagents in neat water

Imidazolium substituted quinoxaline based zwitterionic Pd(ii) complexes were synthesized and found to be excellent catalysts for carrying out Suzuki–Miyaura cross-coupling reactions in neat water.

Palladium-catalyzed vicinal amino alcohols synthesis from allyl amines by in situ tether formation and carboetherification

Vicinal amino alcohols are important structural motifs of bioactive compounds. Reported herein is an efficient method for their synthesis based on the palladium-catalyzed oxy-alkynylation, oxy-arylation, or oxy-vinylation of allylic amines. High regio- and stereoselectivity were ensured through the in situ formation of a hemiaminal tether using the cheap commercially available trifluoroacetaldehyde in its hemiacetal form. The obtained compounds are important building blocks, which can be orthogonally deprotected to give either free alcohols, amines, or terminal alkynes.
