Request PDF | On May 1,Asiye Nas and others published Novel 4-(2-(benzo[d]thiazolyl)phenoxy) substituted phthalocyanine derivatives: Synthesis, electrochemical and in situ. A two step efficient and practical synthesis of a variety of 4-chromanones is described.

Phenols undergo a Michael addition to acrylonitriles in the presence of catalytic amounts of potassium. Knoevenagel methodology can be used to synthesize 2H-pyrans from 1,3-dicarbonyl compounds and α,β-unsaturated choice of base, catalyst, and solvent are important to Phenoxy-2H-Benzo book unwanted side reactions.

A mixture of alkyl-2H-pyran 5-carboxylates 9 and their corresponding dienones are formed in good yield, using sodium benzoate in the presence of triethylbenzylammonium chloride (TEBAC.
