Abstract
The invention provides a method for preparing 1,4-di-tert-butyl-2,5-bis(2-methoxyethoxy)benzene, the method comprising reacting 2,5-di-tert-butylbenzene-1,4-diol with cesium carbonate and halogenated ether in dimethyl formamide. The method yields 500 gram batches at a time, or multiples thereof. The method enables the industrial production of redox shuttles for use in lithium ion battery systems.
