Copper catalysed preparation of vinyl ethers from unactivated vinylic halides
Vinylic halides have been treated with sodium methoxide in the presence of 10 mol% of copper bromide. Most of the vinylic methyl ethers could thus be obtained in a good yield. The reaction proceeds with a 100% retention of configuration. The mechanism of

Peterson Olefination of (α-Methoxybenzyl)silane with Aldehydes and Ketones Leading to Vinyl Ethers
(α-Methoxybenzyl)trimethylsilane is deprotonated with butyllithium and then allowed to react with a variety of carbonyl compounds giving vinyl ethers which are convertible into methyl ketones under mild conditions.
