A catalyst comprising transition metal nanoparticles, stabilizing ligands, and a support material, wherein at least a portion of the stabilizing ligands are adsorbed on the surface of the transition metal nanoparticles such as to form stabilized transition metal nanoparticles, wherein the stabilized transition metal nanoparticles are supported on the support material, wherein the catalyst displays a molar ratio of the stabilizing ligands to the transition metal in the nanoparticles calculated as the element, wherein the molar ratio is comprised in the range of from 0.1 to 25.

The subject invention pertains to a method of halogenating phenols, yielding a range of halogenated phenols with enantiomeric ratio of up to 99.5:0.5. In certain embodiments, the subject invention pertains to a method of asymmetric halogenation of bisphenol, yielding a range of chiral bisphenol ligands. The novel chiral bisphenols are potent privileged catalyst cores that can be applied to the preparation of ligands for various catalytic asymmetric reactions. The catalyst library can easily be accessed because late-stage modification of the scaffold can readily be executed through cross-coupling of the halogen handles on the bisphenols.
