Abstract

Abstract The reaction of elemental sulfur and five diynes of general formula PhC≡ C (G), C≡ CR has been studied. While 1-(1-propynyl)-2-phenylethynylbenzene 1b reacted at 120° C to give solely 6-methylbenz [b] indeno [2, 1-d]-thiopyran 2b, 1, 1′-(1, 2-phenylene) bis (3- phenyl-2-propyn-1-one) 4 and 1, 8-bis (phenylethynyl) naphthalene 5 yielded the sulfides 11, 11′-thiobis-(6-phenyl-5, 12-naphthacenedione) 9 and 12, 12′-thiobis (7- ...
