REACTION OF 6-ARYL-2,2-DIMETHYL-1,3-DIOXIN-4-ONES WITH CYANOAMINO COMPOUNDS
Aroylketenes have been generated by thermolysis of 6-aryl-2,2-dimethyl-1,3-dioxin-4-ones.They take part in a 1,4-cycloaddition reaction at the CN bond of N-aryl or N,N-dialkyl-N-cyanoamines and of N'-phenyl-N-cyanoguanidine to form the corresponding 2-
