    • For consistency, all reactions in Fig. 2 have been run for 22 h. Some isomerization reactions may require shorter reaction time to reach the indicated yields. Nevertheless, if the isomerizations are run for longer period of time, the yields are not improved. For allylic alcohols 3a-e, reactions have been scaled up to a 2 mmol scale using 2b without erosion of neither the yields nor the enantioselectivities Isomerization of (Z)-configured primary allylic alcohols is still problematic with these (P,N)-iridium catalysts. Low conversions and enantioselectivities along with substantial competing (E)/(Z) isomerization were obtained. See also ref. 2 and 4a
