Examples of alicyclic frameworks containing a cyclohexa-1,3-diene ring as 2H donor held proximate to a variously-substituted acceptor Π-bond are compared for their reactivity in thermal 2H group-transfer reactions. Kinetic analysis reveals marked effects on rearrangement-rate as the acceptor Π-bond substieuents are varied. Attempted synthesis of exact structural analogues of these compounds but with
