Abstract

1, 4-Diphenyl-and 1, 4-bis (4-chloropheny1)-1, 4butanediones (3 and 4), as well as 1-phenyl- , 1-(4-chloropheny1)-, and 1-(4-methoxypheny1)-1, 4-pentanediones (7-9) react with bis (tributyltin), bis (tricyclohexyltin), and/or bis-(triphenyltin) sulfide in the presence of boron trichloride to give, 2, 5-diaryl-or 5-methyl-2-arylthiophenes.
