资源简介：
Highly
enantioselective cobalt-catalyzed hydrogenation of 1,1-diarylethenes
was developed by using bench-stable chiral oxazoline iminopyridine–cobalt
complexes as precatalysts. A unique o-chloride effect
was observed to achieve high enantioselectivity. Easy removal as well
as further transformations of the chloro group make this protocol
a potentially useful alternative to synthesize various chiral 1,1-diarylethanes.
This process can be successfully performed under 1 atm of hydrogen
at room temperature on gram scale.
