Abstract:
We carried out Ritter-type reactions using two kinds of cationic tellurium activators. Compared with the trivalent dianisylmethyltelluronium cation, the divalent telluroviologen derivatives showed higher activity and better stability. Telluroviologen activator could cleave the C-OH bond of benzhydrol and the reaction was accelerated under LED light irradiation.

Conjugated systems containing an even number of π-electron pairs undergo a conrotatory ring closure. For example, thermal electrocyclization of (2E,4E)-2,4-hexadiene, a conjugated diene containing two π-electron pairs, gives trans-3,4-dimethylcyclobutene.
