Methods for the synthesis of complex compounds under the conditions of gas-phase reactions, oxidative dissolution of zero-valent metals in non-aqueous media, and in the solid phase have been developed. These methods have become the basis of a new field in synthetic chemistry - the direct synthesis of coordination and organometallic compounds from zero-valent metals. PParticular aspects of the above problem have been described in a series of reviews and monographs. However, on the whole these main parts of the direct synthesis of metal complexes has not been dealt with in the review and monograph publications on coordination chemistry.-
