Transformation of the carboxyl group adjacent to the (η4-diene)Fe(CO)3 moiety: a convenient route to (η4-diene)Fe(CO)3 complexes containing α,β- and β,γ-unsaturated carbonyl groups, and 1,3-dicarbonyl groups
摘要:
Acyl halides adjacent to an (eta(4)-diene)Fe(CO), moiety react with allylsilanes, vinylsilanes and enamines to give the corresponding allyl ketones, vinyl ketones and 1,3-diketones in high yields, respectively. The allylation reaction proceeds smoothly under neutral conditions without a Lewis acid as an activating agent, while the vinylation reaction takes place in the presence of a Lewis acid.
