experimental part, p. 87 - 92 (2012/03/11)
New Hoveyda-Grubbs type catalyst containing nitrochromenyl ligand is reported herein. The catalyst was tested in model RCM, CM and enyne reactions. Its activity was compared with that of commercially available complexes and with literature data for Grela catalyst. New catalyst appeared to be fast initiating, but less stable than other catalysts.
The use of metal reagents in stereo- and regioselective functionalizations of conjugated dienes
Baeckval, Jan-E
, p. 665 - 670 (2007/10/02)
Conjugated dienes have been selectively functionalized via 1-acetoxy-4-chloro-2-alkenes and via 2-(phenylsulfonyl)-1,3-dienes.In both these approaches nucleophiles can be added to the 1- and 4-positions.It was shown that also non-stabilized carbon nucleophiles (from cuprates or copper(I)-catalyzed Grignard reactions) can be used.The utility of the functionalizations was demonstrated by the syntheses of a marine natural product and a butterfly pheromone.Finally, the 2-(phenyl-sulfonyl)-1,3-dienes show a dual electron demand in Diels-Alder reactions and give cycloadducts with both electron-rich and electron-deficient olefins.
"PALLADIUM COMPLEXES-KF / ALUMINA" CATALYSED EXCHANGE OF ALLYLIC GROUPS OF ESTERS WITH PHENOL
Muzart, J.,Genet, J.-P.,Denis, A.
, p. C23 - C28 (2007/10/02)
In the presence of KF/alumina and catalytic amounts of palladium complexes, phenol reacts with allylic esters under mild conditions to give the corresponding allyl phenyl ethers.
