SELECTIVITY IN CYCLOADDITIONS-X. REGIOCHEMISTRY OF CYCLOADDITIONS OF NITRILE OXIDES TO THIOPHENE AND BENZOTHIOPHENE 1,1-DIOXIDES

Albini, F. Marinone,Ceva, P.,Mascherpa, A.,Albini, E.,Caramella, P.

, p. 3629 - 3639 (2007/10/02)

Thiophene-1,1-dioxide undergoes regioselective cycloaddition to benzonitrile oxide.In the reaction with the less reactive mesitonitrile oxide the sulfur dioxide deriving from the dimerization of the dipolarophile causes a catalytic decomposition of the ni
