Can you tell me detailed methodology of the se mechanism. And how it has done

As far as I know there is no confirmed mechanism for Se induced dehydrogenation but all that can be said is that Se is a hydrogen acceptor and forms hydride. When heated with Se hydrocarbon tend to lose hydrogen so as to form conjugated or aromatic system that is thermodynamically favourable.
