Structure of Organolithium Derivatives

An examination of the size (1.34 A), electronegativity (0.97), and electronic structure of lithium show that this element differs substan- 

The molecular weight data given in Table VII show that dimers, tetramers, and hexamers all exist in solution. It appears that under suitable conditions equilibria exist among these species, 

The first observation which one can make is that the degree of aggregation for the alkyl derivatives is largely determined by the size of 

1 With increasing concentration, the degree of aggregation increases. 

Three structural types [XXII (74), XXIII (125, 126), and XXIV (101, 134)] for organolithium compounds have been observed by X-ray
