Abstract: It has been found that the main product of an acid-catalyzed cyclization of 1-chloroacetyl-1'-cinnamoylferrocene is 2-chloro-3-phenyl[5]ferrocenophane-1,5-dione. The acid-catalyzed reaction of 1-acetyl-1'-chloroacetylferrocene with benzaldehyde gives, in addition to 2-chloro-3-phenyl[5]ferrocenophane-1,5-dione, also its acetylation product. Reactions of other 1-acetyl-1'-acylferrocenes with benzaldehyde give also similar acetyl derivatives.
