Carbenes and radicals are among the most important reactive
intermediates.[1]
However, very little is known about their
cross-reaction--the addition of a radical to a carbene to yield
a new radical. This is mainly due to the generally short life-
time of these species which normally prevents the build up of
sufficiently high concentrations of both species in the same
reaction vessel. This situation has changed with the synthesis
of stable carbenes 1.[1b]
Yet, except for a single study on the
addition of a muonium to 1,[2]
very little is known on this
fundamentally important reaction. To study such reactions
the correct type of radicals has to be used. Radicals (YC) need
