Aldehydes and Ketones Form Intermediate pi Complexes with the Gilman Reagent, Me2CuLi, at Low Temperatures in Tetrahydrofuran
Typical aldehydes and ketones form pi complexes with Me2CuLi at low temperatures in tetrahydrofuran. They range in stability from fleeting intermediates at -100 degrees C to entities that persist up to -20 degrees C. Three subsequent reaction pathways have been identified.
