Ru/Pd Complex and Its Monometallic Fragments as Catalysts for Norbornene Polymerization via ROMP and Addition Abstract: The [Ru(PPh3)2Cl-piperidine(4-aminomethyl)] complex (mono-Ru) was synthesized from [Ru(PPh3)3Cl2] and 4-(aminomethyl)piperidine, whereas the [(PPh3)PdCl(Shiff-pip)] complex (mono-Pd) was obtained by reacting […]
Dual catalytic performance of arene-ruthenium amine complexes for norbornene ring-opening metathesis and methyl methacrylate atom-transfer radical polymerizations Abstract: Arene ruthenium(II) complexes bearing the cyclic amines RuCl2(eta(6)-p-cymene)(pyrrolidine)] (1), [RuCl2(eta(6)-p-cymene)(piperidine)] (2), and [RuCl2(eta(6)-p-cymene)(peridroazepine)] (3) were successfully synthesized. […]
Nucleophilic Addition of Amines to Ruthenium Carbenes: ortho-(Alkynyloxy)benzylamine Cyclizations towards 1,3-Benzoxazines Abstract: A new ruthenium-catalyzed cyclization of ortho-(alkynyloxy)benzylamines to dihydro-1,3-benzoxazines is reported. The cyclization is thought to take place via the vinyl ruthenium carbene intermediates which […]
Atom Transfer Radical Polymerization of Methyl Methacrylate Mediated by Grubbs 1st and 2nd Generation Catalysts: Insight into the Active Species Abstract: Ruthenium benzylidene complexes were evaluated as catalysts in atom-transfer radical polymerization (ATRP) of methyl methacrylate […]
Atom transfer radical polymerization by [RuCl2(PPh3)2(amine)] catalysts: Cyclic amines as tuner of reactivity Abstract: Atom transfer radical polymerizations (ATRP) of styrene (St) and methyl methacrylate (MMA) mediated by [RuCl2(PPh3)2(amine)] complexes, with amine = pyrrolidine (1), piperidine (2), or […]
