Effect of hydroxy-functionalized ionic liquids on the palladium-catalyzed Heck reaction
1-(2,3-Dihydroxypropyl)-3-methylimidazolium hydroxide ([glymim]OH), 1-hexyl-3-methylimidazolium hydroxide and 1-butyl-1,8-diazabicyclo[5.4.0]undec-7-ene hydroxide ionic liqs. were used as co-catalysts in the Pd-catalyzed Heck reaction of PhBr with CH2=CHCOOBu. The highest yield of PhCH=CHCOOBu (60%) was obtained for [glymim](2)[PdCl4] complex at 140 degrees C in Me2NCHO.
