Abstract
The present invention is a process for the preparation of bis(1,2-diaryl-1,2-ethylenedithiolato)-nickel-based complex which is characterized by reacting a benzil-based compound or a benzoin-based compound with phosphorus pentasulfide in 1,3-dimethyl-2-imidazolidinone and successively reacting with nickel chloride.
