Vinyl iodides have been treated with various copper(I) derivatives (aryl- and alkyl-copper derivatives, copper(I) chloride, cyanide, bromide, thiolate) and found to undergo substitution at carbon with retention of configuration. Copper(II) carboxylates give much better yields of enol esters than the corresponding copper(I) salts. A four centre mechanism accounts best for the results.

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 the process is shortly discussed.
