The design of catalysts for asymmetric propargylations remains a challenging task, with only a handful of methods providing access to enantioenriched homopropargylic alcohols. In this work, guided by previously reported computational predictions, a set of

It takes two to tango! A combination of partially reduced chiral H 8-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.
