主　　题：Benzo-[b]-pyran dimetone ethylene glycol. 

摘      要：A series of tetrahydrobenzo-[b]-pyran derivative was synthesized by the reaction of arylmethylene malononitrile or arylmethylene cyanoacetate with dimedone in ethylene glycol at 80C without catalyst. The structures of the two products were characterized by X-ray diffraction.
