The Selective Elimination of Secondary Alkyl Group from Trialkylborane by the Successive Treatments with Anisole and Dimethyl Sulfoxide. A Supply of the Synthetic Intermediate for Primary Alkyl Derivatives

Secondary alkyl group of trialkylborane, derived from terminal olefin and borane, was selectively eliminated by the successive treatments with anisole and dimethyl sulfoxide. By the use of the resulting trialkylborane as the synthetic intermediate for primary alkyl derivatives, the contaminations of secondary alkyl derivatives were greatly reduced.
