An alkyl(phosphine)copper complex performed alkylative ring opening of a monosubstituted epoxide, but not that of a 1,2-disubstituted or trisubstituted epoxide, and, upon reaction with this complex, a diepoxy compound comprising terminal and internal epoxy functionalities in a single molecule formed a product based on preferential attack at the terminal functionality.
