Abstract

A mild and efficient alkoxide-catalyzed addition of ferrocenylacetylene to diverse ketones and aldehydes is described. Some new propargyl alcohols containing ferrocenyl moieties were obtained by addition of ferrocenylacetylene to ketones. When aromatic aldehydes were used, trans-enones such as ferrocenyl chalcone derivatives were obtained in high yields via base-catalyzed addition-isomerization.

Key words

ferrocenylacetylene - propargylic alcohols - aromatic aldehydes - enones - alkynylation.
