Nickel‐catalyzedthree‐componentcoupling reactions of tetrafluoroethylene, aldehydes, and silanes are reported. Mechanistic studies revealed that the oxa‐nickelacycles generated via the oxidative cyclization of TFE and aldehydes were key intermediates for the catalytic reactions. The obtained products can be effectively transformed into the valuable trifluorovinyl compounds and organo silyl compounds

s to the C=O bond of aromatic aldehydes in the presence of cesium fluoride to give the corresponding“silylated” alcohols in high yields was performed. The reactivity of the “silylated” alcohols in the presence of nucleophilicreagents and Bronsted acids was studied. On the basis of isolated compounds and of intermediates detected by NMR spectroscopic methods, several reaction pathways are proposed
