Title: Theoretical Study on Associated States of Methyllithium Clusters
　　　　　
Abstract:
 Alkyllithium, an organometallic reagent, is a strong base and is a very
useful compound in organic synthesis as nucleophilic reagents. It is known
that the structure in solvents exists as various associated states.
Previously, it has been studied using experimental methods such as X-ray
analysis and it has considered that methyllithium exists as tetramer in
major. However, it is difficult experimentally specify the associated states
in liquid phase.
 In this study, I investigated the associated states of methyllithium
clusters for isolated system and crystal structure as the first step using
some of the calculation methods in order to theoretically specify in liquid
phase. I will report the present condition and views in future.
