title: Generation, direct observation, and kinetics of triplet 9-(1,1,4,4,5,5,8,8-octamethyl-1,2,3,4,5,6,7,8-octahydro- anthryl)phenylcarbene.
abstract: [structure: see text] Reactivities of the title triplet carbene were compared with those of the "untied" counterpart, [2,4,6-tris(tert)butylphenyl](phenyl)carbene. An appreciable increase in the stability of triplet carbene is noted by tuning the distance between the o-hydrogen and the carbene center.
