Controlled dilithiation of propargyl bromide with two equivalents of n-butyllithium, in the presence of TMEDA, produces the operational equivalent of the dianion 1,3-dilithiopropyne. The latter reacts efficiently with ...

Several aromatic homopropargyl alcohols, and derivatives were prepared by one-pot reaction of 1,3-dilithiopropyne (or its equivalent) with aldehydes and ketones. The antibacterial activity, of alcohols ...

The title compound, C 22 H22 O 5, crystallizes with two molecules in the asymmetric unit, one of which shows disorder of its ethyl acetate group over two sets of sites in a 0.880 (2):0.120 (2) ratio. The C C distances ...

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 ...

A regiospecific palladium-catalyzed cross-coupling reaction using the operational equivalent of the dianion 1,3-dilithiopropyne, with aromatic iodides is reported. This reaction gives high yields of 1-propyn-1-yl-benzenes ...

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. ...
