transfer: The electron‐rich iron complex Bu4N[Fe(CO)3(NO)] efficientlycatalyzes different carbene‐transfer reactions. Various diazo compounds can be used. The high stability of the employed iron complexes is demonstrated by the generation of the diazo reagent in situ and a sequential iron‐catalyzed allylic sulfenylation/Doyle–Kirmse reaction.

catalyze the Doyle-Kirmse reaction of allyl sulfides with (trimethylsilyl)diazomethane and ethyldiazoacetate in dichloroethane at 83 degrees C. Competitive dimerization is less of a problem with (trimethylsilyl)diazomethane than with ethyldiazoacetate. Good results are obtained using only 1.5 equiv of (trimethylsilyl)diazomethane, even without slow addition. Phosphine ligands affect the kinetics, but

Trimethylsilyldiazomethane is compared with ethyl diazoacetate for the rhodium, copper, and cobalt catalyzed formation and [2,3] rearrangement of allylsulfonium ylides. At room temperature, the reaction can be carried out using the allyl sulfide as the limiting reagent by slow addition of 3 equivalents of the diazo compound. Slightly better yields were obtained with trimethylsilyldiazomethane than
