In the crystal, 3 adopts a conformation with an almost coplanar (phi = 163 degrees) 1,3-diene core, with the inner vinylcyclopropane units in an orthogonal and the outer vinylcyclopropane moieties in an s-trans orientation. This diene, like 2,3-cyclopropylbuta-1,3-diene (5), undergoes facile concerted [4+2] cycloadditions at 130 degrees C with dimethyl acetylenedicarboxylate as well as N-phenylmaleimide and at 0 degrees C with N-phenyltriazolinedione. An X-ray crystal structure analysis of 2,3-dicyclopropylbuta-1,3-diene (5) also reveals a coplanar inner core with the vinylcyclopropane units in essentially orthogonal (phi(av)=89.3 degrees) orientation.
