3-Arylcarbostyrils, coumarins and thiacoumarins (3) have been prepared from the respective β-aryl-α-bromodihydrocinnamoyl derivatives (2) by treatment with AlCl3.The β,β-diarylacrylic acid derivatives (4) and (9), obtained from 2, on reaction with AlCl3 afford 4-arylcarbostyrils (5) 6-methyl-4-phenylthiacoumarin (10) respectively.However the oxygen analogs (11) give 3,3-diphenyl-1-indanone (12)
