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.
