CYCLOADDITION OF ANHYDRO BASES OF HETEROCYCLIC CATIONS. 1. SYNTHESIS OF SPIROHETARENES IN THE REACTION OF s-TETRAZINES WITH THE ANHYDRO BASES OF ACRIDINIUM, XANTHYLIUM, AND THIOXANTHYLIUM SALTS
A new method of spiro-ring formation by the reaction of s-tetrazines with anhydro bases was described.The prototropic transitions were detected in the pyridazine fragments of the resulting spirocyclic compounds.The heterocycles of the anhydro bases are co
