-
(RSC Publishing, 2010)The expansion of the concept of N-heterocyclic carbenes as ligands for transition metals to mesoionic ligand systems has led to the discovery of a wide range of non-classical carbene-type ligands. These non-classical ...
-
(RSC Publishing, 2010-01-14)Abnormal C4-bonding of N-heterocyclic carbenes effectively modulates the electron density at rhodium and allows for the selective cleavage of an unactivated C(sp3)–H bond, whereas no such intramolecular C–H bond breaking ...
-
The Potential of N-Heterocyclic Carbene Complexes as Components for Electronically Active Materials (Swiss Chemical Society, 2010-03)The application of N-heterocyclic carbene complexes as active sites in materials other than catalysis has been remarkably scarce. Inspired by the — often misleading — ‘carbene’ label, which implies a substantial degree of ...
-
(Elsevier, 2010-03-31)An efficient one-pot synthesis is described for the preparation of 1,4-disubstituted piperazine-2,5-diones starting from a suitable amine and chloroacetyl chloride in the presence of an aqueous base. The resulting chlo ...
-
(RSC, 2010-07-10)[FeII(C16dpt)2(NCS)2]·⅔H2O displays temperature-mediated spin crossover (SCO) with T½ = 290 K and the long alkyl chain substituent on the dipyridyltriazole ligand facilitates the formation of a stable Langmuir-Blodgett ...
-
(RSC Publishing, 2010-08)Using microwave irradiation, water soluble, optically active, penicillamine (Pen) capped CdSe nanocrystals with broad spectral distribution (430-780 nm) of photoluminescence have been produced and studied by a range of ...
-
(Elsevier, 2010-08)Pt/BaO/Al2O3 catalysts react with NO/O2 mixtures to form barium nitrites and nitrates. In the presence of small amounts of C(s) admixed with the catalyst the concentrations of NOx adsorbed is considerably reduced and the ...
-
(Elsevier, 2010-10-13)The use of I2/AgOAc in dichloromethane constitutes a cheap, mild, and efficient method for the selective iodination of a variety of heterocycles. In a number of cases, this method provides superior yields than other ...
-
(ACS, 2010-10-22)We report a thorough investigation of a series of isomeric complexes with the general formula trans-(pyridylidene)M(PPh3)2Cl (M = Pd, Ni). For the first time, a systematic comparison of normal, abnormal and remote bonding ...
-
(RSC Publishing, 2011)The quaternarized pdppz derivative 1 was shown to bind strongly to DNA with concomitant changes in its ground and excited state photophysical properties. Furthermore, the compound also showed rapid cellular uptake, and ...
-
(Springer, 2011)The wastewater generated at a facility specialising in potato processing was found to contain high levels of insoluble potato starch. Several separation methods were employed to obtain maximum potato starch recovery from ...
-
(ACS Publications, 2011-03)The role of N1-substitution in controlling the deactivation processes in photoexcited cytosine derivatives has been explored using picosecond time-resolved IR spectroscopy. The simplest N1-substituted derivative, ...
-
(RSC publicating, 2011-06-16)The catalytic water oxidation activity of mononuclear ruthenium complexes comprising a pyridine-functionalized abnormal triazolylidene ligand can be adjusted by modification of the triazolylidene substituents, which is ...
-
(Elsevier, 2011-08-01)The coupled δ13C-radiocarbon systematics of three European stalagmites deposited during the Late Glacial and early Holocene were investigated to understand better how the carbon isotope systematics of speleothems respond ...
-
(Elsevier, 2011-10)This work has studied a range of acidic catalysts which have been prepared through the modification of mesoporous silica materials. Specifically we have prepared –SO3H modified materials (in the presence and absence of a ...
-
(Elsevier, 2011-10-11)CexZr1−xO2 catalysts with various Ce/Zr contents were studied using Raman spectroscopy under different gaseous atmospheres, at different temperatures and in the presence of a model soot. Catalysts with high concentrations ...
-
(Elsevier, 2011-12)Central to understanding how nanoscale objects interact with living matter is the need for reproducible and verifiable data that can be interpreted with confidence. Likely this will be the basis of durable advances in ...
