Generation and characterization of triplet anthryl(aryl)carbenes.
The title carbenes where aryl groups are phenyl, 2,4, 6-trimethylphenyl, and octahydro-1,4:5,8-di(ethano)anthryl were generated for the first time by irradiation of the corresponding diazo precursors and fully characterized by ESR in a rigid matrix at low temperature. It has been demonstrated that anthryl groups can act as excellent reservoirs for the unpaired electrons as well as relatively effective kinetic protectors for carbene.
