Abstract

Reaction of magnesium-arene compounds,[Mg (anthracene)(THF),], 1, and some silylanthracene, and/or tertiary amine analogues, with benzylic and allylic chlorides or bromides, and (Me3Si), CC1, afford Grignard reagents, RMgX, in modest to high yield for chlorides and negligible to high yield for the bromides, in THF, toluene, and hexane at-10 to 20 “C. Novel benzylic-type Grignard reagents prepared in high yield include those of 9-( ...
