4‐Acetyl[2.2]paracyclophane ( 1 ) is converted into the nitrone 2 by treatment with N ‐methylhydroxylamine·hydrochloride. When 2 is reacted with ( E )‐1,2‐dibenzoylethene ( 4 ) the pyridinyl[2.2]paracyclophane 13 is formed in a novel condensation reaction. The structures of 2 and 13 , and the mechanism of formation of the latter are discussed. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2005)
