Abstract Biologically active nitrogen heterocycles (1–7) containing ferrocene and quinuclidine fragments were synthesized. 3-Methylene-2-ferrocenylmethylenequinuiclidine forms adducts withN-phenylimides of azodicarboxylic (the structure was established by X-ray structural analysis) and malefic acids. 3-Methylene-2-fer-rocenylmethylenequinticlidine also undergoes [4+2]-cyclodimerization when heated and adds salts of the 3-methyl-2-ferrocenylmethyleneI-azoniabicyclo[2.2.2]oct-3-yl cation at the terminal methylene group to form a linear addition product.
