Less-Common Methods of the “Direct Synthesis” Area

Abstract

In this chapter, we describe several methods that are common for other types of reactions, but are rare in the synthesis of coordination and organometallic compounds. Certain attention is paid to micrometer-size Rieke metals, a very popular research field before the nanotechnology era. Other methods include the ultrasonic treatment, intercalation, laser ablation sputtering, use of ammonia in distinct forms, and the oxidative dissolution of elemental metals in non-aqueous media. It is concluded that the majority of these techniques, widely used in the decade 1980–1990, have been forgotten, although their further use could lead to novel coordination compounds, which are unavailable by classic chemical routes.
