Yamagami T, Shintani R, Shirakawa E, Hayashi T
Org Lett . 2007 Feb; 9(6):1045-8. PMID: 17291003
Addition of arylmagnesium bromides to aryl(alkyl)acetylenes proceeded in the presence of an iron catalyst and a N-heterocyclic carbene ligand to give high yields of the corresponding alkenylmagnesium reagents, which were...

Org Lett . 2006 Oct; 8(21):4799-801. PMID: 17020306
[reaction: see text] A rhodium-catalyzed multicomponent-coupling reaction has been developed that involves a cross-coupling with organohalides as part of the reaction sequence. Through several experiments toward mechanistic investigations, it has...

J Am Chem Soc . 2005 Dec; 127(49):17164-5. PMID: 16332046
Iron and copper complexes cooperatively catalyzed the arylmagnesiation of unfunctionalized alkynes including dialkylacetylenes, where the presence of both iron and copper catalysts is essential for high yields of 2-aryl-1-alkenylmagnesium bromides.

Org Lett . 2005 Nov; 7(23):5317-9. PMID: 16268567
[reaction: see text] The first catalytic asymmetric synthesis of 2-aryl-2,3-dihydro-4-quinolones has been developed by way of a rhodium-catalyzed 1,4-addition of arylzinc reagents to 4-quinolones. These 1,4-adducts can be obtained with...
