10534-59-5, Tetrabutylammonium acetate is a catalyst-ligand compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
To a solutionof 5 (1 mmol, 1 eq.), 1-bromo-3,5-dimethoxybenzene(1.5 eq.), TBAA (6.0 eq.), Pd(OAc)2 (0.1 eq.) were dissolvedin 2 cm3 of NMP under an argon atmosphere. The wholewas heated at 110 C for 24 h. After cooling, a saturatedsolution of Na2CO3 was added and the resulting solutionwas extracted thrice with ethyl acetate. The organic layerswere then dried over Na2SO4 and evaporated to give anoil, from which residual NMP was evacuated using a lyophilizer.Chromatography of the resulting oil on silica geleluted with hexane/ethyl acetate (v/v: 60/40) gave 7 (tracesin these conditions). Further elution gave 6 in 75% yield asan orange oil.
