Abstract
In one or more embodiments, the present invention is directed to a novel method for synthesizing Mg(BHT)2(THF)2 catalyst, which has several advantages over previous methods. Dry toluene or pentane are not required for synthesizing the catalyst, and the reaction is done in a bulk solution of BHT and THF. Further, because the Mg(BHT)2(THF)2 is made in a one-step (“one-pot”) synthesis, the time required for synthesizing and drying the catalyst is reduced. Using the new method of the present invention, the Mg(BHT)2(THF)2 is pure after removing excess THF, thereby eliminating the need for washes and recrystallization.
