The catalytic cycle involves in the first step the decomposition of the diazo derivative to afford the reactive [RuCl(Cp){=C(R-1)R-2}] intermediate and a mechanism is proposed for this step based on a kinetic study of the simple coupling reaction of ethyl diazoacetate. The evolution of the Ru-carbene intermediate in the presence of alkenes depends on the nature of the substituents at both the diazo N-2=C(R-1)R-2 (R-1, R-2 = Ph, H; Ph, CO2Me; Ph, Ph; C(R-1)R-2 = fluorene) and the olefin substrates R-3(H)C=C(H)R-4 (R-3, R-4 = CO2Et, CO2Et; Ph, Ph; Ph, Me; Ph, H; Me, Br; Me, CN; Ph, CN; H, CN; CN, CN). A remarkable reactivity of the complex was recorded, especially towards unstable aryldiazo compounds and electron-poor olefins. The results obtained indicate that either cyclopropanation or metathesis products can be formed: the first products are favoured by the presence of a cyano substituent at the double bond and the second ones by a phenyl." ; prodottidellaricerca:prodottoDi modulo:ID2555 , istituto:CDS023 ; pubblicazioni:autoreCNR unitaDiPersonaleInterno:MATRICOLA2505 . @prefix parolechiave: . prodotto:ID18506 parolechiave:insiemeDiParoleChiave . parolechiave:insiemeDiParoleChiaveDi prodotto:ID18506 .
