Azoles reacting in tandem: The ortho‐stereodirecting effect is the key to the stereoselective synthesis of (Z)‐N‐alkenylazoles I through the tosylhydrazide‐mediated Pd‐catalyzed cross‐coupling reaction of α‐N‐azoleacetophenones with ortho‐substituted aryl halides and nonaflates (see scheme). Additionally, the preorganization of the alkene allowed for the development of an auto‐tandem reaction involving
