A series of diphosphoramidites has been synthetized with a piperazine, homopiperazine, and an acyclic 1,2-diamine unit in the backbone. New compounds were tested alongside related -acyl phosphoramidites as ligands in the Rh-catalyzed hydroformylation of -octenes to investigate their influence on the activity and regioselectivity. A subsequent study of their hydrolysis stability revealed that the most stable ligands induced the highest activity in the catalytic reaction.

Article Synopsis
  • * A new dual ligand-relay catalysis approach is proposed, involving a two-step, one-pot process that uses two biphosphite ligands to enhance the reaction efficiency and selectivity.
  • * This method achieved up to 65.9% selectivity for adipic aldehyde, with full conversion of 1,3-butadiene, surpassing previous catalysis systems, and also produced 26.5% selectivity for -valeraldehyde as a useful byproduct.

Chiral diphosphines with a biphenyl bridge and the chirality borne by the phosphorus atoms and not due to the atropoisomery of the biaryl backbone have been scarcely studied. Herein, we report the asymmetric synthesis of the (,)-2,2'-bis(ferrocenylphenylphosphino)biphenyl (BipheP*) ligand and its application in Rh-catalyzed hydrogenation. The synthesis was based on the enantioselective preparation of P-chirogenic ferrocenyl(-bromophenyl)phenylphosphine by the reaction of -phosphine-borane with 1,2-dibromobenzene and its homocoupling into BipheP*.

Enantioselective hydrogenation of olefins by Rh-based chiral catalysts has been extensively studied for more than 50 years. Naively, one would expect that everything about this transformation is known and that selecting a catalyst that induces the desired reactivity or selectivity is a trivial task. Nonetheless, ligand engineering or selection for any new prochiral olefin remains an empirical trial-error exercise.

Highly enantioselective Rh-catalyzed allylic substitution of the racemic branched allylic substrates with 2-fluoromalonate was realized enabled by a novel chiral sulfoxide-imine-olefin ligand under mild reaction conditions. The utilization of CuSO is beneficial for improving the enantioselectivity. Notably, the chiral fluoro-containing allyl products can be employed in a selective cyclic esterification to form chiral α-fluorolactone bearing vicinal stereogenic centers.

Revealing key factors that modulate the regioselectivity in heterogeneous hydroformylation requires identifying and monitoring the dynamic evolution of the truly active center under real reaction conditions. However, unambiguous in situ characterizations are still lacking. Herein, we elaborately construct a series of Rh-POPs catalysts for propylene hydroformylation which exhibited tunable regioselectivity.
