The highly regio- and enantioselective iron-catalyzed anti-Markovnikov hydroboration of 1,1-disubstituted aryl alkenes is reported by using a novel chiral iminopyridine oxazoline (IPO) ligand, in which the iminopyridine group is proposed to stabilize the iron and chiral oxazoline group to control enantioselectivity. This distinct class of reactive IPO ligands will likely be of high value for a large variety of asymmetric transformations using first-row transition metals.

Tough nut to crack: Chiral bidentate N-heterocyclic carbene copper complexes were designed that promote enantioselective hydroborations of one of the most difficult substrate classes: acyclic and exocyclic 1,1-disubstituted alkenes undergo reaction with >98% site selectivity, in up to >98% yield and e.r=96.5:3.5 (see scheme, B2(pin)2 = bis(pinacolato)diboron).
