Controlling the pirouetting motion in rotaxanes by counterion exchange
(American Chemical Society, 2014-07-25)
A fine control of the pirouetting motion of rotaxanes was achieved by using a series of metallabisdicarbollides. The latter were used as anions in the protonated form of benzylic amide macrocycle-containing fumaramide ...
The pyrolysis of 2-methylfuran: a quantum chemical, statistical rate theory and kinetic modelling study
(Royal Society of Chemistry, 2014-01-27)
Due to the rapidly growing interest in the use of biomass derived furanic compounds as potential platform chemicals and fossil fuel replacements, there is a simultaneous need to understand the pyrolysis and combustion ...
Rate constant calculations of H-Atom abstraction reactions from ethers by H(O) over dot(2) radicals
(American Chemical Society, 2014-01-31)
In this work, we detail hydrogen atom abstraction reactions from six ethers by the hydroperoxyl radical, including dimethyl ether, ethyl methyl ether, propyl methyl ether, isopropyl methyl ether, butyl methyl ether, and ...
Bodipy-ruthenium(II) tris-bipyridyl dyads for homogeneous photochemical oxidations
(Elsevier, 2014-10-28)
Two Bodipy-ruthenium(II) tris-bipyridyl dyads were synthesized for use as sensitizers in photochemical oxidation reactions of organic substrates. The synthetic strategy involved the use of a simple ‘click’ CuAAC reaction ...
H2 generation and sulfide to sulfoxide oxidation in H2O using sunlight with a model photoelectrosynthesis cell
(Elsevier, 2014-10-28)
A summary of the recent advances in homogeneous light-driven catalytic oxidation reactions is provided either using sacrificial agents or with complete functional cells. In this work, a photoelectrosynthesis model cell ...
Widely applicable metallacarborane reagents for π-conjugated systems
(American Chemical Society, 2014-05-12)
The compounds [N(CH3)4][3,3′-Co(8-(p-C6H4C2H3)-1,2-C2B9H10)(1′,2′-C2B9H11)], [N(CH3)4][3,3′-Co(8-(p-C6H4CHO)-1,2-C2B9H10)(1′,2′-C2B9H11)], and [N(CH3)4][3,3′-Co(8-(m-C6H4CHO)-1,2-C2B9H10)(1′,2′-C2B9H11)] were synthesized ...
Synthesis of fluorinated alkoxyamines and alkoxyamine-initiated nitroxide-mediated precipitation polymerizations of styrene in supercritical carbon dioxide
(Royal Society of Chemistry, 2014-06-20)
TIPNO (2,2,5-trimethyl-4-phenyl-3-azahexane-3-nitroxide)-alkoxyamine was found to give reasonably controlled/living nitroxide-mediated (NMP) precipitation polymerizations of styrene in supercritical carbon dioxide (scCO(2)). ...
Chain transfer to solvent in the radical polymerization of structurally diverse acrylamide monomers using straight-chain and branched alcohols as solvents
(Royal Society of Chemistry, 2014-01-02)
Chain transfer to solvent in conventional radical polymerizations of N-tert-butylacrylamide (TBAM) and N-(2-morpholin-4-ylethyl) acrylamide (MEA) in a range of alcohol solvents is investigated. Mayo analysis of polymerization ...
Tandem reactions via Barton Esters with intermolecular addition and vinyl radical substitution onto indole
(American Chemical Society, 2014-05-16)
A one-pot initiator-free Barton ester decomposition with tandem radical addition onto alkyl propiolates or phenylacetylene with aromatic substitution of the resultant vinyl radical allows convenient access to new 9-substituted ...
Using rapid compression machines for chemical kinetics studies
(Elsevier, 2014-04-26)
Rapid compression machines (RCMs) are used to simulate a single compression stroke of an internal combustion engine without some of the complicated swirl bowl geometry, cycle-to-cycle variation, residual gas, and other ...
