✦ Synopsis
The relative reactivities of the 3,4_dimethylenethiophene intermediates 1 from the deazetation of the diazene 5 and from the intramolecular cyclization of bisallenyl sulfide 3, determined by competition experiments, serve as a "fingerprint" to show that the same reactive transient is generated from both precursors.
