G. Simonneaux et al., Ruthenium-porphyrin-catalyzed carbenoid addition to allylic compounds: application to [2,3]-sigmatropic rearrangements of ylides, J ORGMET CH, 617(1), 2001, pp. 360-363
The catalytic effectiveness of ruthenium porphyrins for ylide generation in
reactions of ethyl diazoacetate and diisopropyl diazomethylphosphonate wit
h allylic amines, sulfides and iodides is described for the first time. The
se reactions result mainly in products of the [2,3]-sigmatropic rearrangeme
nt of intermediate allylic ylides. (C) 2001 Elsevier Science B.V. All right
