Remarkable metal ion catalysis of methanolysis of O,O′-oxybis(ethyleneoxyethylene)-tert-butylcalix[4]arene monoacetate
Abstract
Basic methanolysis of the cone-isomer of O,O′-oxybis(ethyleneoxyethylene)-tert-butylcalix[4]arene monoacetate 2 is accelerated more than a millionfold by barium and strontium ions.
