摘要:
[9-{10-Phenyl}anthryl](4-bromo-2,6-dimethylphenyl)diazomethane was found to be stable enough to survive Sonogashira coupling reaction conditions and was converted to [9-{10-phenyl}anthryl](4-trimethylsilyiethynyl-2,6-dimethylphenyl)diazomethane, which was reacted with 1,8-dliodoanthracene to give bis(diazo) compound. Bis(carbene) generated by irradiation of the bis(diazo) compound generated a fairly persistent S = 2 quintet state.
