A series of (1-propynyl)arenes were prepared by one-pot double elimination reaction of ethyl sulfone, aromatic aldehyde and chloro diethylphosphate in THF with a base such as BuLi and t-BuOK. A propargyllithium which was prepared by treatment of (1-propynyl)arene with BuLi in the presence of 1,3-dimethyl-3,4,5, 6-tetrahydro-2(1H)-pyrimidinone (DMPU) reacted with aromatic aldehyde, chloro diethylphosphate and t-BuOK to afford (4-arylbut-3-en-1-ynyl)arene. Photoluminescence of the enynes thus prepared was recorded both in solution and in the solid state. Georg Thieme Verlag Stuttgart.

The reaction of elemental sulfur and five diynes of general formula PhCC(G)nCCR has been studied.While 1-(1-propynyl)-2-phenylethynylbenzene 1b reacted at 120 deg C to give solely 6-methylbenzindenothiopyran 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-phenylbenzo-fluoranthene) 13, respectively, as the major products.Diyne 5 gave also a small amount of bis(7-phenylbenzofluoranthene-12-yl)disulfide 14. 3,3'-Oxybis(1-phenyl-1-propyne) 6 did not react in the absence of a metallic additive, but yielded 4,6-diphenyl-1H,3H-thienofuran 15 in the presence of equimolar quantities of RhCl3*3H2O and Aliquat-336.The reaction of the conjugated diyne 1,1'-(1,3-butadiyne-1,4-diyl)bisbenzene 7 with sulfur afforded 3,6-diphenyldithiolo-1,2-dithiole 16. Key words: Sulfur addition to diynes; benzindenothiopyran; dithiolo-1,2-dithiole; polycyclic sulfides; polycyclic disulfides.
