Nickel catalyzed dealkoxylative C(sp2)-C(sp3) cross coupling reactions--stereospecific synthesis of allylsilanes from enol ethers.

The application of cyclic and acyclic enol ethers as electrophiles in cross coupling reactions offers new possibilities for the preparation of functional compounds. A novel nickel catalyzed dealkoxylative cross coupling reaction allows access to structurally diverse allylsilanes and alcohol derivatives with high stereospecificity and in good yields under mild reaction conditions directly from the corresponding enol ethers.
