  Half-sandwich ruthenium(II) complexes of aminophosphines: synthesis, structures and catalytic applications in C–C coupling reactions between styrenes and diphenyldiazomethane

  摘要：

  The half-sandwich Ru(II) complexes of the type [CpRu(PPh2N(H)R)(PPh3)Cl], [CpRu(PPh2N(H)R)(2)Cl] (R = Ph, C6H11) and [CpRu(PPh2N(R')PPh2-kappaP,kappaP)(PPh3)]Cl (R' = Et, Pr-n, Pr-i, Bu-n), were synthesized and the structures of complexes [CpRu(PPh2N(H)Ph)(PPh3)Cl] and [CpRu(PPh2N(H)Ph)(2)Cl] were confirmed by single crystal X-ray diffraction studies. All ruthenium complexes were employed in the cyclopropanation reaction of styrene derivatives in the presence of diphenyldiazomethane. All complexes afford 1,1,3,3-tetraphenyl cyclobutane along with cyclopropane derivatives; complex, [CpRu(PPh2N(Bu-n)PPh2-kappaP,kappaP)(PPh3)]Cl shows better selectivity in the formation of 1,1,2-triphenylcyclopropane. In all reactions appreciable amounts of cyclopropanation products and metathesis products, 1,2-diphenylcyclopropane and 1,1-diphenylethene were obtained along with 1,1,3-triphenylpropene derivatives. The variable temperature NMR studies have suggested that the cyclopropanation reactions in the presence of ionic complex, [CpRu(PPh2N(R')PPh2-kappaP,kappaP)(PPh3)]Cl proceeds via carbene intermediate, [CpRu(= CPh2)(Pph(2)N(R')PPh2-kappaP)(PPh3)]Cl.
