Synthesis of heteroleptic pyrrolide/bipyridyl complexes of ruthenium(II)
(2012-08)The synthesis and characterization of the first heteroleptic pyrrolide/2,2'-bipyridyl complexes of ruthenium(II) are reported. Pyrroles substituted at the 2-position with X = O functionality react with Ru(bipy)(2)Cl-2.2H(2)O ... -
Synthesis of natural products containing the pyrrolic ring
(2010)This review provides an overview of the synthetic chemistry that has been utilised to prepare natural products containing a pyrrolic ring. -
Synthesis of Prodigiosene-Estrogen Conjugates: optimization of protecting group strategies and anticancer properties
(Canadian Journal of Chemistry, 2015)The tripyrrolic prodigiosene skeleton was conjugated to several estrogen ligands. The conjugation was achieved via an ester linker that proved to be unusually sensitive to hydrolysis during synthesis. This work describes ... -
Synthesis of symmetric meso-H dipyrrin hydrobromides from 2-formyl pyrroles
(Synlett, 2014)The reaction of 2-formyl pyrroles in acidic methanol gives the corresponding symmetric, meso-H 4,6-dipyrrin hydrobromides. This convenient strategy involves initial deformylation under the acidic conditions, followed by ... -
Synthesis, Lithium Insertion and Thermal Stability of Si–Mo Alloys
(The Electrochemical Society, 2020-10-05)Li insertion was investigated in SixMo100−x (90 ≥ x ≥ 70, Δx = 10) alloys prepared by mechanical ball milling. X-ray diffraction (XRD) and quantitative phase analysis were used to analyze phase compositions of these Si–Mo ... -
Synthesis, properties and reactivity of BCl2 aza-BODIPY complexes and salts of the aza-dipyrrinato scaffold
(Royal Society of Chemistry, 2020-02-25)The synthesis and characterisation of the BCl2-chelated complexes of both archetypal aza-dipyrrin sub- types are presented. A stepwise halogen exchange, leading to a mixed-halide Cl–B–F intermediate, is implicated in the ... -

Synthetic studies toward the kempane diterpenes. Construction of a key tricyclic intermediate
(2005)A synthetic sequence is described for construction of the tricyclic portion (35) of kempane diterpenes. The central stereochemistry was established by a Diels-Alder addition of 2,6-dimethyl-para-benzoquinone to a 5-membered, ... -

Technique for determination of accurate heat capacities of volatile, powdered, or air-sensitive samples using relaxation calorimetry
(2006-09)We introduce a four-step technique for the accurate determination of the heat capacity of volatile or air-sensitive samples using relaxation calorimetry. The samples are encapsulated in a hermetically sealed differential ... -
Temperature dependence of thermal conductivity enhancement in single-walled carbon nanotube/polystyrene composites
(2010-02)The thermal conductivity of single-walled carbon nanotube (SWCNT)/polystyrene composites, prepared by a method known to produce a uniform distribution of SWCNT bundles on the micrometer length scale, was measured in the ... -
Temperature dependent lattice misfit and coherency of Al3X (X = Sc, Zr, Ti and Nb) particles in an Al matrix
(Elsevier, 2015-05-01)The lattice coherency and critical radii for Al3X precipitates in an aluminum matrix were computed using first-principles methods. From density functional perturbation theory and the quasi-harmonic approximation, the unit ... -

Thermal and lattice dynamical properties of Na8Si46 clathrate
(2001-07)The experimental heat capacity of Na8Si46 has been determined from 35-300 K, and its lattice parameters have been measured over the range 100-330 K. The experimental heat capacity and the thermal-expansion coefficient ... -
Thermal conductivities of a clathrate with and without guest molecules.
(1992)The thermal conductivities of Dianin's compd. [4-(p-hydroxyphenyl)-2,2,4-trimethylchroman] and its ethanol adduct in the temp. range 20-250 K are reported. This clathrate has the same stable structure both with and without ...
