Miao, Weishi,Chung, Lung Wa,Wu, Yun-Dong,Chan, Tak Hang
, p. 13326 - 13334 (2004)
The transient organoindium intermediates formed in the reaction of propargyl bromide with indium in aqueous media and tetrahydrofuran were investigated by NMR spectroscopy and found to be allenylindium(I) and allenylindium(III) dibromide. The influence of
Photoredox propargylation of aldehydes catalytic in titanium
Calogero, Francesco,Gualandi, Andrea,Di Matteo, Marco,Potenti, Simone,Fermi, Andrea,Bergamini, Giacomo,Cozzi, Pier Giorgio
, p. 7002 - 7009 (2021/05/29)
A practical and effective photoredox propargylation of aldehydes promoted by 10 mol % of [Cp2TiCl2] is presented. No stoichiometric metals or scavengers are used for the process. A catalytic amount of the cheap and simply prepared or
Acid-catalyzed synthesis of α,β-disubstituted conjugated enones by a Meyer-Schuster-type rearrangement in allenols
Alcaide, Benito,Almendros, Pedro,Cembellín, Sara,Martínez Del Campo, Teresa

A novel, direct and simple methodology to gain access to α,β-disubstituted conjugated enones from α-allenols in a sustainable metal catalysis context, considering the inexpensiveness and environmentally friendliness of iron(III) species and protons, has b
Carbonyl allenylations and propargylations by 3-chloro-1-propyne or 2-propynyl mesylates with tin(IV) chloride and tetrabutylammonium iodide
Masuyama, Yoshiro,Watabe, Akiko,Kurusu, Yasuhiko
, p. 1713 - 1715 (2007/10/03)
By the use of tin(IV) chloride and tetrabutylammonium iodide in dichloromethane, 3-chloro-1-propyne or 2-propynyl mesylate can be applied to allenylation and propargylation of aldehydes (carbonyl allenylation and propargylation) to produce a mixture of 1-
On pentaorganylstiborane. III. Regio- and diastereoselective additions of acetylenic and allenic organoantimony compounds to aldehydes
Zhang, Li-Jun,Mo, Xue-Sheng,Huang, Yao-Zeng
, p. 77 - 86 (2007/10/02)
The reaction of propargyl bromide (4a) with tributylstibine gave allenyltributylstibonium bromide (5), and its corresponding pentaorganylstiborane reacted with aldehyde to give homopropargylic alcohol (10a) exclusively in good yield.However, the reaction
Selective Synthesis of Allenic and Acetylenic Derivatives via Pentaorganylstiboranes
Zhang, Li-Jun,Huang, Yao-Zeng,Huang, Zhe-Hui
, p. 6579 - 6582 (2007/10/02)
Allenyltetrabutylstiborane (3), formed from allenyltributylstibonium bromide (2) and butylmagnesium bromide, reacted with aldehydes to give homopropargylic alcohols (4) exclusively in excellent yields, while 2-butynyltetrabutylstiborane (6), formed from 2
