Abstract

Benzylic and allylic alcohols were deoxygenatively dimerized by a treatment with lanthanum metal and chlorotrimethylsilane in the presence of a catalytic amount of iodine, giving the corresponding coupling products, alkanes, in moderate-to-good yields. This dimerization reaction was dramatically accelerated by the addition of a catalytic amount of copper (I) iodide. Similarly, ethers and esters were deoxygenatively dimerized by La/Me 3 SiCl/cat. I ...
