This reaction gives rise to separation problems which may be overcome by the use of a large excess of SO 2 and/or by the addition of suitable organic solvents. The results obtained with SO 2 only and with addition of diethylether and TBP are discussed, also in view of application of ...
The reaction was stereospecific, with retention of configuration at the 7′-position. However, it was complicated by a concurrent partial isomerization of the dihydrothiazine double bond from the Δ-3,4 (cephalosporin numbering) to the Δ-2,3 position, forming a separable mixture (3:1) of 47...

The reaction rate constants and diffusion coefficients obtained for the synthetic systems all follow the Arrhenius relation. Exchange reactions with natural sulphides give lower exchange rates, different equilibrium values, and more scattered plots. These deviations can be explained by lattice distortions ...
The hydrogen and oxygen isotope composition of waters at Libiola and Vigonzano agrees with their meteoric origin. Acid to neutral mine waters do not show any significant isotope shift with respect to the initial water, in spite of the oxidation of even large amounts of pyrite/chalcopyrite ore....
