When an element possesses more bonds than is expected by the octet rule, it is labeled as hypervalent. I recommend all the students in our lab to make presentations in domestic/international conferences about once a year to express our research results to the world. A combination of partially reduced chiral H8-TBOx chromium catalyst 1 and achiral cobalt porphine co-catalyst 2 (Ar=*p *-anisyl) led to an enhancement in enantioselectivity by suppression of the background process that presumably proceeds through an organomanganese species.
