for the formulation of the cyclo-octatetraene tetramer as 1. Thus tetracyano-ethylene gives a 2:1 adduct 7, and at ca 310° the tetramer fragments cleanly to afford the cyclo-octatetraene dimer 9. Additions to dimer 9 may be effected selectively at the 4,5-double bond, and occur in the exo-mode. The generation of tetrachlorobenzyne from 3,4,5,6-tetrachlorobenzenediazonium carboxylate in tetrahydrofuran
已经获得了将环辛酸酯四聚体配制为1的补充证据。因此,四氰基乙烯产生2:1的加合物7,并且在约310°下,四聚体片段干净地得到环辛八烯二聚体9。可以在4,5-双键处选择性地实现对二聚体9的加成,并且以exo-模式发生。在四氢呋喃中由3,4,5,6-四氯苯重氮羧酸盐生成四氯苯并生成醚-酯22。
