Cycloisomerization of homopropargylic thiols to dihydrothiophenes is promoted by group VI metal carbonyls. Related thiacyclization transformations under basic and radical conditions are also described, including regioselective formation of benzothiophenes from aryl methyl sulfides and alkynes.
4-Alkynylphenyl imidazolylpropyl ethers as selective histamine H3- receptor antagonists with high oral central nervous system activity

In search for potent and therapeutically useful H3-receptor antagonists, we prepared novel 4-alkynylphenyl ether derivatives of 3-(1H- imidazol-4-yl)propanol in a convenient synthetic route. All compounds were tested for in vitro and in vivo H
Choix des methodes pour la synthese univoque de carbures acetyleniques. Troisieme partie : Arylacetylenes et aryl-1 alcynes-1

The range of applicability of six syntheses of pure alkynes with one aryl group has been defined; a short review of other possible procedures is included.We have specified the best method to obtain selectively the alkynes Ar-CCH and Ar-CC-R, according to the nature of the substituents of the aryl group and according to the developed structure of the R group.It is thus possible to recommend with the largest probability of success the method to obtain, in homogenous series, alkynes corresponding to still more complicated structures.
