Diiodosamariura prepared in THP reduces allylic iodides and bromides at 0 or -15 °(7 to give organosamarium compounds which are stable under these conditions. These allylic samarium compounds react with many functionalities including the keto group of keto esters. Benzylic samarium compounds were pr
2-Phenylsulphonyl cyclic ethers undergo facile displacement of the sulphonyl group by alcohols, in the presence of magnesium bromide etherate and sodium bicarbonate in tetrahydrofuran, to give good yields of the corresponding acetals. The preparation of tetrahydro-pyran and -furan ethers typically
