Abstract

When used in non-coordinating solvents (hydrocarbons) NaAlEt4 and LiAlnBu4 are good alkylation agents for epoxides. The presence of catalytic quantities of transition-metal salts, particularly NiCI2 or NiBr2, greatly accelerate the reactions, making them possible within a reasonable time in the case of disubstituted epoxides such as cyclohexene oxide, 2-3 epoxybutane, 1 phenyl-2, 3-epoxybutane. In the case of aliphatic epoxides, ...
