Sub room temperature differential vapor pressure osmometry: A method for the determination of the aggregation number of α-heterosubstituted organolithium compounds and lithium amides in solution

The aggregation number of α-Selenium- and α-Sulfur-substituted organolithium compounds, lithium amides, and transition metal complexes in solution has been determined by sub room temperature differential vapor pressure osmometry. This novel method allows measurements of oxygen, moisture, and temperature sensitive compounds. The aggregation number of these compounds can be determined in THF solutions at 0°C and in diethyl ether solutions at -35°C. by Oldenbourg Wissenschaftsverlag, Muenchen.

Equilibrium Lithium Ion Pair Acidities of 2-Phenyl-1,3-dithiane and 2-p-Biphenylyl-1,3-dithiane: A New Approach

A new technique has been developed to measure the equilibrium ion pair acidities of 2-phenyl-1,3-dithiane (1) and 2-p-biphenyly-1,3-dithiane (2) with lithium as counterion.The lithium ion pair pK values (pKLi/THF) in tetrahydrofuran (THF) at 25 deg C were determined to be 29.4 (1, contact ion pair (CIP)), 28.2 (2, CIP), and 29.3 (2, solvent separated ion pair (SSIP)), as compared to the values of 30.5 (1, CIP) and 29.1 (2, CIP) measured previously with cesium as counterion.At 25 deg C, the lithium salt of 2-p-biphenylyl-1,3-dithiane (2L) exists as a mixture of CIP, SSIP, and free ion, with the ratio of / = 11.4.The results are consistent with the stronger electrostatic interactions between lithium cation and the dithianyl anion for CIP than for SSIP, resulting in a lower pKa for CIP.The equilibrium constant of SSIP ->/0 = 1.43 kcal mol-1, ΔS0 = 9.6 eu.The SSIP of 2L was found to dissociate significantly to the free ion in dilute THF solution.The measured dissociation constants of 2L to the free ion at 25 deg C are (1.22 +/- 0.08)E-6 M and (1.39 +/- 0.09)E-5 M for CIP and SSIP, respectively.The slow transmetalation reactions of 1 and 2 with different lithium indicator anions also allowed the measurements of some kinetic rate constants at 25 deg C, from which Broensted β values were obtained for 1 and 2.
