Both the conrotatory processes for the thermal electrocyclic conversion of ( 2 E , 4 E ) -2, 4- hexadiene into 3 , 4- dimethylcyclobutene is to be shown. An explanation as to why the two processes are equally likely is to be stated. Concept introduction: Electrocyclic reactions are pericyclic reactions which takes place by concerted mechanism. These reactions involve ring opening or ring closure in a conjugated polyene. In conrotatory, the end group atomic orbital rotates in a clockwise direction.
