The phosphorus ylides RPh 2 P=C(Mes)N=C(CF 3 ) 2 [R = Ph, Ph 2 P(O)CH 2 ] in solution undergo reversible dissociation of the P=C ylidic bond to give phosphanes RPh 2 P and the carbene MesC( : )N=C(CF 3 ) 2 . The latter can be trapped as its mesomeric nitrile ylide by treatment with cyclohexene or phenyl isocyanate to give cyclic addition products. (© Wiley‐VCH Verlag GmbH & Co.
