Chloride ion, derived from 2,3-dichloro-5,6-dicyanohydroquinone (DDHQ), was found to participate in opening of the 2,2'-anhydro bond of 5,6-dihydropyrimidine nucleosides, but not their 5,6unsaturated counterparts. The increased basicity of the nucleosidic nitrogen is believed to be a factor in this
