1,3-Enyne structural motifs are versatile building blocks in organic synthesis and occur widely in various natural products with many of them being highly active as cytotoxic macrolides and antitumour antibiotics. This ...

The title compound, C9H7NO2, was prepared by alkynylation of 4-iodo­nitro­benzene with 1,3-dili­thio­propyne in the presence of 1 equivalent of CuI and catalytic amounts of Pd(PPh3)2Cl2. The complete mol­ecule is generated ...

The asymmetric unit of the title homopropargyl alcohol, C20H16OS, contains two independent molecules comprising a hydroxy group, a 3-(2-thiophenyl)- propargylic moiety and two aromatic rings linked to a central carbon atom. ...

In the title compound, C17H16O2, the central carbon atom has a distorted tetra­hedral geometry [spread of angles = 105.71 (8)–112.75 (9)°] for its bonds to a homopropargylic but-2-yn-1-ol moiety, a hy­droxy group and two ...

The asymmetric unit of the title compound, C16H14O, contains one mol­ecule with a central carbon atom having a distorted tetra­hedral geometry made of a propargylic fragment, a hy­droxy group and two aromatic rings. ...
