Rhenium- and gold-catalyzed coupling of aromatic aldehydes with trimethyl(phenylethynyl)silane: Synthesis of diethynylmethanes
Kuninobu, Yoichiro,Ishii, Eri,Takai, Kazuhiko
, p. 3296 - 3299 (2007)
(Chemical Equation Presented) Very couply! Coupling reactions of propargyl or benzyl alcohols with allyl- or alkynylsilanes proceed efficiently using [{ReBr(CO)3(thf)}2] as catalyst. Additionally, diethynylmethane derivatives were obtained by the reaction of aromatic aldehydes with trimethyl(phenylethynyl)silane in the presence of both the rhenium complex and AuCl (see scheme).
Highly enantioselective phenylacetylene additions to both aliphatic and aromatic aldehydes.

The readily available and inexpensive BINOL in combination with Ti(O(i)Pr)(4) is found to catalyze the reaction of an alkynylzinc reagent with various types of aldehydes including aliphatic aldehydes, aromatic aldehydes, and other alpha,beta-unsaturated a
TTMPP-catalyzed addition of alkynes using trimethylsilylacetylenes
Matsukawa,Sekine
experimental part, p. 1718 - 1721 (2009/10/01)
A highly basic phosphine, tris(2,4,6-trimethoxyphenyl)phosphine (TTMPP), catalyzes alkynylation using trimethylsilylalkyne to give the corresponding products in good to high yields. Copyright Taylor & Francis Group, LLC.
Chiral macrocycle-catalyzed highly enantioselective phenylacetylene addition to aliphatic and vinyl aldehydes
Li, Zi-Bo,Liu, Tian-Dong,Pu, Lin
, p. 4340 - 4343 (2008/02/05)
(Chemical Equation Presented) The 1,1′-binaphthyl macrocycle (S)-2 is found to be an excellent catalyst for the alkyne addition to aldehydes. In the presence of (S)-2 (20 mol %) and Me2Zn (2 equiv) in THF at room temperature, the addition of ph
Alkynylation of carbonyl compounds with terminal acetylenes promoted by ZnCl2 and Et3N: Simple, mild and efficient preparation of propargylic alcohols
Jiang, Biao,Si, Yu-Gui
, p. 8323 - 8325 (2007/10/03)
A mild and efficient addition of terminal acetylenes to carbonyl compounds in the presence of ZnCl2 and Et3N gives propargylic alcohols in good to high yields.
ALDEHYDE-SELECTIVE ADDITION OF ALKYNYLCHROMIUM COMPOUNDS PREPARED BY REDUCTION OF ALKYNYL HALIDES WITH CHROMIUM(II) REAGENT
Takai, Kazuhiko,Kuroda, Tooru,Nakatsukasa, Shigeki,Oshima, Koichiro,Nozaki, Hitosi
, p. 5585 - 5588 (2007/10/02)
Alkynyl halides are reduced by chromium(II) chloride in DMF to give unisolable alkynylchromium compounds which add selectivity to an aldehyde moiety without affecting the coexisting ketone group of the substrate.
