Triethylsilylcobalt tetracarbonyl in the reaction with isobutyraldehyde formed Silyl enol ether. The cleavage of isobutyrylcobalt tetracarbonyl with triethylsilane gives (triethylsilyl)cobalt tetracarbonyl, isobutyraldehyde, dicobalt octacarbonyl, and the corresponding unsaturated and saturated silyl ethers.
