摘要: Resume Cyanohydrins of aliphatic aldehydes are converted into ethers by benzylic bromides with phase transfer catalysis to give β-benzylic α'-cyanoethers. On treatment lithium di-isopropylamide, these compounds o-methylaryl ketones via a [2.3]-sigmatropic rearrangement the resulting carbanions and elimination cyanide.
