A facile method for the preparation of bishomopropargylic alcohols from acyl chlorides
(2014)
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 ...
Synthesis and Antibacterial Activity of Aromatic Homopropargyl Alcohols
(2017)
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 ...
Homopropargyl alcohol 1,1-diphenylbut-3-yn-1-ol
(2018)
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. ...
Homopropargyl alcohol 1,1-diphenylbut-3-yn-1-ol
(2018)
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. ...
Homopropargyl alcohol 5,5-diphenylpent-2-yne-1,5-diol
(2018)
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 ...

Palladium-Catalyzed One-Pot Conversion of Aldehydes and Ketones into 4‑Substituted Homopropargyl Alcohols and 5‑En-3-yn-1-ols
(2017)
Sequential treatment of 2,3-dichloropropene
with magnesium and n-BuLi generated the equivalent of 1,3-
dilithiopropyne, which adds regiospecifically to aldehydes and
ketones to produce homopropargyl alcohols. The ...
A new method for the preparation of 1,3-dilithiopropyne: an efficient synthesis of homopropargyl alcohols
(2001)
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 ...
Ethyl 5-[(ethoxycarbonyl)oxy]-5,5-diphenylpent-2- ynoate
(2019-11-12)
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 ...
1,1-Diphenyl-4-(thiophen-2-yl)but-3-yn-1-ol
