[η3-η5-(Silyloxy–alkenyl)]-cobalt carbonyls and various silyl ethers were formed in the cobalt carbonyl mediated silylations of α,β-unsaturated and aromaticcarbonylcompounds. A silyloxonium tetracarbonylcobaltate tight ion pair was suggested as a common intermediate, which provides the products through a radical pair in the cases of aromatic aldehydes and ketones.
