Abstract
Adding non-redox metal ions to simple Pd(OAc)2 catalyst can remarkably promote oxidative dehydrogenation of saturated CC bond, and the activity improvement is Lewis acidity strength dependent. Through UV–vis and NMR characterizations of the catalyst, it was proposed that in-situ generated heteronuclear Pd(II)/Zn(II) dimer is the key active species for dehydrogenation.
