Abstract

The invention relates to a method for preparing compounds of the general formula M^AY_n(AzuH) (I), where M^A=alkali metal, Y=neutral ligand, n=0, 1, 2, 3, or 4. AzuH is azulene (bicyclo[5.3.0]decapentaene) or an azulene derivative that bears a hydride anion H− in the 4, 6 or 8 position in addition to an H atom. The invention additionally provides compounds obtainable by this method, and a method using such compounds for preparation of complexes of metals of groups 6 to 12. The invention further relates to complexes of middle and later transition metals (groups 6 to 12) which each have at least one H-dihydroazulenyl anion (AzuH)¹−, and to the use of all the aforementioned transition metal complexes as precatalysts or catalysts or electron transfer reagents in a chemical reaction or as precursor compounds for production of a layer containing a metal M, or of a metal layer consisting of the metal M, especially on at least one surface of a substrate. The invention also provides a substrate obtainable by such a method. 25
