Coupling of diazonium salts with ethyl sulfonylpyruvates 1-3 or arenesulfonylacetic acids 14,15 afforded good yields of the corresponding 1,5-symmetrically disubstituted-3-sulfonylformazans 4-1 1. The new sulfonyl macrocyclic crown formazans 25-32 were prepared by coupling of the appropriate bisdiaz

## Abstract Opal–inverse opal interlocked composites consisting of opals of hollow spheres with window channels interlocked, have displayed new properties. A facile and general method has been reported to synthesize the ordered composites. Polymer shells are first grown onto the surface of a silica
clo[6.1 .O]nonatriene has been interpreted by a participation of an aromatic transition state. The ca. 7 kcal/mol lower Gibbs activation energy of ( l a ) -(24 would accordingly suggest an aromatic transition state for the bicyclopentene rearrangement. We assume, however, that the lower activation b
