Fig. 2: Asymmetric reduction of chromium η6-arene complexes.
From: Asymmetric hydrogenation of 1,1-diarylethylenes and benzophenones through a relay strategy
a Synthesis and Corey-Bakshi-Shibata (CBS) reduction of Cr(CO)3 benzophenone complex. b Relative stability of Cr(CO)3 arene complex. c This work: synthesis of compounds bearing a chiral gem-diaryl motif from either 1,1-diarylethylenes or benzophenones by a sequence involving selective arene exchange and stereoselective asymmetric hydrogenation.
