Acetylation of B15C5 crown ether on Cu modified clay catalysts

Article abstract of DOI:10.1016/0040-4039(95)02399-2

With different copper-clay based catalysts, in the presence of AcCl as acetylation agent, B15C5 crown ether is acetylated in a convenient heterogeneous catalytic procedure. We show here the first heterogeneous catalytic method for crown ether acylation, where the Cu exchanged clay gives the best results using really catalytic amount of catalyst.
