Synthesis of Propan-1,3-diones and Chromens

摘要

The present work deals with the synthesis 1-(2-hydrbxy-3,4-benzophenyl)-3-styryl-propanT1,3-diones(3a-3a),2-bromo/iodo-1-[2-hydroxy-3,4-benzophenyl)-3-styryl-propan-1,3-diones(4a-4f),2-styryl-7,8-benzophenyl chromones(5a-5c),3-bromo/iodo-2-styryl chromones(6a-6f).Structure of these compounds were established on the basis of element analysis spectral analysis(IR,~(13)C NMR).
