Copper-catalyzed cross-coupling of alkyl and aryl grignard reagents with alkynyl halides
Cahiez, Gerard,Gager, Olivier,Buendia, Julien
supporting information; experimental part, p. 1278 - 1281 (2010/05/18)
(Chemical Equation Presented) Good old copperl A new general procedure to couple aliphatic and aromatic Grignard reagents with alkynyl halides under copper catalysis is described (see scheme; NMP=N-methylpyrrolidinone). The reaction is chemoselective and allows preparation of a vast array of simple and functionalized internal alkynes in high yields.

The carbonylation of alkanes 1 under radical-reaction conditions was examined by using ethynyl triflone A as the unimolecular chain-transfer (UMCT) reagent. Good to moderate yields of ethynyl ketones 2 were prepared by means of this three-component coupli
SUBSTITUTION OF THE HYDROXYL GROUP IN ACETYLENIC ALCOHOLS BY HYDROGEN
Libman, N. M.,Shandybina, O. N.
, p. 2290 - 2293 (2007/10/02)
Tertiary α-alkynols containing at least one phenyl group at the acetylenic carbon atom are reduced by trialkyl- and triarylsilanes in the presence of trifluoroacetic acid to the corresponding acetylene hydrocarbons.
Photoelectron Spectra of Phenylethynes, I. - Phenylethyne - Model Probe for Substituent Effects
Elbel, Susanne,Lienert, Klaus,Krebs, Adolf,Dieck, Heindirk tom
, p. 1785 - 1797 (2007/10/02)
The four low energy ?-orbitals of ethynylbenzene (1) respond differently to substitution at the alkyne site due to their respective symmetry properties.The gas phase He(I) PE spectra of the series 1 - 13 (C6H5-CC-R) are presented and the energetic tren
POLYMETALLIC DERIVATIVES OF ARYL-SUBSTITUTED ALKYNES. IX. THE PMR SPECTRA OF METALLIC DERIVATIVES WITH VARIOUS STRUCTURES IN THE SIDE CHAIN
Libman, N. M.,Dmitrieva, T. L.,Kuznetsov, S. G.,Andreev, A. A.
, p. 231 - 241 (2007/10/02)
The PMR spectra of the products from the metallation of a series of arylalkynes and arylallenes with potassium amide in liquid ammonia were investigated.It was shown that the majority of these compounds are deprotonated to form phenylpropargyl monometalli
