Reaction of tetracarbonyl(π-allyl)manganese with carbon nucleophiles
摘要:
Nucleophilic attack on tetracarbonyl(pi-allyl)manganese takes place at the terminus of the pi-system, generating allylated products in 44-95% yield after oxidation. Stabilized nucleophiles (pK(a) 12-20) give mainly his allylation whereas nonstabilized nucleophiles (pKa 25-35) give mono allylation. (C) 1997 Elsevier Science Ltd.

The rate of ethylation by Et2SO4 of potassium enolate of ethylacetoacetate is enhanced in the presence of polymers bearing -pyrrolidone —N.P.) or -oxazolidone (—N.O.) moieties. It depends on the nature of the polymeric skeleton. The C/O alkylation as well as the ratio E/Z of the enolethers gives an account of the interaction of the enolate with its associated cation inside the polymer: the efficiency
