allylation product in the presence of a catalytic amount of the (cyclooctadiene)rhodium(I) chloride dimer [Rh(cod)Cl]2}, sodium tetrakis[3,5-bis(trifluoromethyl)phenyl]borate (NaBARF), and triphenyl phosphite [P(OPh)3] in refluxing 1,2-dichloroethane. Primary, secondary and tertiary benzyl acetates could be used for the reaction. Moreover, allylation of gem-benzyl acetate was possible with [Rh(cod)Cl]2, NaBARF

The synthesis and characterization of silicon Lewis acid complexes that incorporate highly electron-deficient cyclopentadienes is reported. Several pentacarboxycyclopentadienyl and monocarboxytetracyanocyclopentadienyl complexes were prepared. A comparison of their reactivities for catalysis of the allylation of an electron-deficient benzaldehyde was established. The use of a monocarboxytetracyano

radical phosphorylation procedures utilizing unconventional initiation modes such as the use of triethylborane [6, 7] and transition metal compounds [8–10]. For instance, the use of manganese(III) acetate as catalyst made it possible to considerably extend the scope of application of radical processes in practical organic synthesis and develop many new procedures for the synthesis of heterocyclic and organoelement
