The scope of the present method turns out not to be limited to aromatic aldehyde derivatives, as cyclohexanecarboxaldehyde undergoes pinacolization as well (44% yield, dl : meso = 93 : 7, 84% ee). Brnsted acid catalysts are able to play an important role in green chemistry. Int. Very reactive species will readily undergo chemical reactions with other species if they are around and unstable species will degrade quickly after they form. 1-Bromoalkynes can be activated by the introduction of a cobalt porphine co-catalyst, which enables shorter reaction times without any loss of enantiocontrol.
