Synthetic Route of 213697-53-1. Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 213697-53-1, Name is 2′-(Dicyclohexylphosphino)-N,N-dimethyl-[1,1′-biphenyl]-2-amine

We describe the development of (eta3-1-tBu-indenyl)2(mu-Cl)2Pd2, a versatile precatalyst scaffold for Pd-catalyzed cross-coupling. Our new system is more active than commercially available (eta3-cinnamyl)2(mu-Cl)2Pd2 and is compatible with a range of NHC and phosphine ligands. Precatalysts of the type (eta3-1-tBu-indenyl)Pd(Cl)(L) can either be isolated through the reaction of (eta3-1-tBu-indenyl)2(mu-Cl)2Pd2 with the appropriate ligand or generated in situ, which offers advantages for ligand screening. We show that the (eta3-1-tBu-indenyl)2(mu-Cl)2Pd2 scaffold generates highly active systems for a number of challenging cross-coupling reactions. The reason for the improved catalytic activity of systems generated from the (eta3-1-tBu-indenyl)2(mu-Cl)2Pd2 scaffold compared to (eta3-cinnamyl)2(mu-Cl)2Pd2 is that inactive PdI dimers are not formed during catalysis.

We report a general palladium-catalyzed beta-arylation of Boc-piperidines, which yields a variety of valuable 3-arylpiperidines in a simple and direct manner. The beta- vs. alpha-arylation selectivity was controlled by the ligand, with flexible biarylphosphines providing mainly the desired beta-arylated products whereas more rigid biarylphosphines mainly furnished the more classical alpha-arylated products. The computed reaction mechanism (DFT), studied from the common alpha-palladated intermediate, indicated that the reductive elimination steps leading to the alpha- and beta-arylated products are selectivity-determining. Moreover, the experimental trend obtained with different ligands was well reproduced by the calculations.

We report the synthesis of air-stable Pd(i) dimer complexes featuring biaryl phosphine ligands. Catalytic experiments suggest that these complexes are competent precatalysts that can mediate cross-coupling amination reactions between aryl halides with both aliphatic and aromatic amine nucleophiles. This work represents an expansion of the air-stable precatalyst toolbox for Pd-catalyzed cross-coupling transformations.
