Catalytic Cyclopropanation of Polybutadienes
Catalytic cyclopropanation of commercial 1,2or 1,4cis-polybutadiene, respectively, with ethyl diazoacetate catalyzed by [TpCu(NCMe)] (Tp 1⁄4 hydrotris(3,4,5-tribromo-1-pyrazolyl)borate) at room temperature afforded high molecular weight (Mn > 10 5 mol ) side-chain or main-chain, respectively, carboxyethyl cyclopropyl-substituted polymers with variable and controlled degrees of functionalization...
متن کاملA new chiral ruthenium complex for catalytic asymmetric cyclopropanation
A new chiral ruthenium complex 6, featured with an N,O-mixed polydentate ligand, was synthesized and characterized. This ruthenium complex showed high efficiency in catalytic cyclopropanations of alkenes with diazoacetates. High trans/cis selectivity and enantioselectivity (up to 96%) were achieved with the readily accessible ethyl diazoacetate as the reagent. © 2002 Elsevier Science Ltd. All r...
متن کاملBidentate carbenoid ester coordination in non-planar ruthenium(II) complexes leading to excellent levels of both diastereo- and enantioselectivity in catalytic alkene cyclopropanation
General experimental details. All organometallic and catalytic procedures were carried out under an inert atmosphere of argon by using a dual manifold vacuum/argon line and standard schlenk techniques, or in an MBraun glove box. All solvents were predried by refluxing for three days under dinitrogen over the appropriate drying agents (sodium for toluene; potassium for THF; sodium-potassium allo...
متن کاملMetalloradical activation of α-formyldiazoacetates for the catalytic asymmetric radical cyclopropanation of alkenes.
For the first time, α-formyldiazoacetates have been successfully applied for the asymmetric cyclopropanation of alkenes via Co(ii)-based metalloradical catalysis. The cobalt(ii) complex of the D2-symmetric chiral amidoporphyrin [Co(3,5-Di t Bu-ChenPhyrin)] is an effective metalloradical catalyst that can activate α-formyldiazoacetates to cyclopropanate both aromatic and aliphatic olefins with v...
متن کاملCatalytic asymmetric addition of carbon dioxide to propylene oxide with unprecedented enantioselectivity.
New chiral catalyst systems were developed for the reaction of carbon dioxide with propylene oxide (PO) at atmospheric pressure to generate enantiomerically enriched propylene carbonate (PC). The best selectivity was achieved with a Co(III)(salen)-trifluoroacetyl complex and bis(triphenylphosphoranylidene)ammonium fluoride (PPN+F-) as catalysts, affording PC in 40% yield and 83% ee (selectivity...
