Thermophysics of thallium alkanoates IV. Heat capacity and thermodynamic functions of thallium(I) n-dodecanoate from 7 to 470 K,
(Elsevier, 1987-12)
The thermal behavior of thallium(I) n-dodecanoate was studied by adiabatic calorimetry from 6 to 350 K and by d.s.c. from 230 through 470 K. The agreement between the results (temperature and thermal functions of transitions ...
Reactions of vinyl selenoxides and ketenes via 3,3-sigmatropic rearrangement
(Elsevier, 1987)
The reactions of several vinyl selenoxides with chlorocyano-ketene proceed a 3,3-sigmatropic rearrangement of an enolate oxyselenonium species to yield seleno-substituted [gamma]-butyrolactones.
Stereoselective acyclic synthesis via allylmetals: Threo vicinal diols from both - and -[gamma]-alkoxyallyltins and aldehydes
(Elsevier, 1987)
Both - and -[gamma]-alkoxyallyltins stereoselectively add to aldehydes in the presence of BF3[middle dot]OEt2 at -78[deg]C in CH2Cl2 to produce the threo (or syn) vicinal diol monoalkyl ether unit.
Thermophysics of metal alkanoates VII. Heat capacities and thermodynamic properties of potassium n-butanoate
(Elsevier, 1987-02)
The subambient heat-capacity curve of potassium n-butanoate as determined by adiabatic equilibrium calorimetry is characterized by a "bifurcated" transition whose "peaks" occur at 123.85 and 142.3 K. The corresponding (Cp, ...
Synthesis and rearrangements of ortho-selenonium phenoxides
(Elsevier, 1987)
A new class of selenonium zwitterions is prepared from the ortho- substitution of phenols with diphenylselenium bis(trifluoroacetate) 1. The zwitterions undergo a novel thermal rearrangement to produce diaryl ethers.
Thermodynamics of copper sulfides I. Heat capacity and thermodynamic properties of copper(I) sulfide, Cu2S, from 5 to 950 K
(Elsevier, 1987-11)
The heat capacity of Cu2S from 5 to 950 K was determined by adiabatic-shield calorimetry and the thermodynamic properties were evaluated. Transitions occur at 376 and about 710 K with [Delta]trsSm = (1.240+/-0.006)R and ...
