3,7-BIS-(4-TRIFLUOROMETHYLPHENYL)-1,5,3,7-DIOXADIAZOCINE: A NOVEL CYCLIC PRODUCT FROM A REACTION OF 4-TRIFLUOROMETHYLBENZENEDIAZONIUM CHLORIDE AND METHYLAMIN-FORMALDEHYDE

Article abstract of DOI:10.1016/S0040-4039(00)98507-1

4-Substituted benzenediazonium chlorides react with methylamine-formaldehyde mixture at -5 to-10 deg C and controlled pH to afford the novel 3,7-bis-(4-X-aryl)-1,5,3,7-dioxadiazocines rather than the expected 1-(4-X-aryl)-3-hydroxymethyl-3-methyltriazenes or related dimeric products.
