Half-life and/or lifetime of the carbene are not mentioned in the literature, see: Ref. 102b.

Generation of dendric hexakis- and dodekakis-(diphenylcarbene) derivatives are also reported. They show low
spin-states due to the connectivities with both non-disjoint ( S = 2, J > 0) and disjoint ( J
0) manners, see:
