1,6-Addition of t-butylmagnesium chloride to anthraquinone
Abstract
Reaction between t-butylmagnesium chloride and anthraquinone takes an unusual course. It gives 3,10-di-t-butyl-10-hydroxyanthrone as the major addition product. Further reaction leads to 3,6,10-tri-t-butyl-10-hydroxyanthrone. These and related examples of 1,6-addition are discussed, as are competing reactions brought about by the Grignard reagent acting as a base
