The conformational behavior of the 2-(diphenylphosphinoyl)-1,3-dithiane was studied in the 258-323 K temperature range. Plots of ln K versus 1/T are linear, permitting evaluation of the enthalpic and entropic contributions of the S-C-P(O) anomeric effect. Comparison with the corresponding thermodynamic data in the cyclohexyl analogue allows estimation of the enthalpic anomeric effect in this system: ca. 3.4 kcal/mol.
