摘要

Conclusions The conformational equilibria of 2-[(4-methoxy-phenyl) seleno]-1, 3-dithiane and the configurational equilibria of the corresponding 4, 6-dimethyl-l, 3-dithianes in various solvents have been examined. Plots of In K vs 1/T using data from both types of experiments are linear and yield values for the enthalpy and entropy differences. The equilibrium data in toluene and chloroform are attributed to specific solvation effects. The preferential ...
