Abstract
This invention resides in a process for production of predominantly a 1,4-O-metallation product of a hydride of silicon, germanium, or tin with an .alpha.,.beta.-unsaturated carbonyl compound. The reaction involved takes place in the presence of a heterogeneous noncomplexed rhodium-containing catalyst. This invention also resides in 1,4-O-metallation compositions having perfluoroalkyl R groups on either side of the C.dbd.C bond of an enol ether or on the acetal side of the C.dbd.C bond of a ketene acetal.
Claims16
