| Abstract: | Copper-induced intramolecular deiodinecoupling reaction of 3, 7-dinitrodibenzocycloiodonium iodides was studied. Three new compounds(2, 7-dinitrobiphenylene, 2, 7-dinitrodibenzofuran and 3, 6-dinitro-9-(4-nitrophenyl)-9H-fluoren-9-ol)were synthesized by the deiodinecouplingreaction. It is suggested that the reaction take place in two steps:(1)thermal decomposition of the cycloiodonium salt(3) to 2,2'-diiodo-4,4'-dinitrodiphenyl compound(4) is followed by (2) Ullmann reaction of 4to the deiodinecoupling product(5). |
