摘要： The invention relates to a method for preparing compounds of the general formula MAYn(AzuH) (I), where MA=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

摘要： The invention relates to a method for producing complexes of precious metals, in particular platinum, which have at least one organo-dihydroazulenyl ligand. The invention also relates to complexes of precious metals, in particular platinum, which have at least one organo-dihydroazulenyl ligand and to the use of the aforementioned metal complexes as precatalysts or catalysts in a chemical reaction or as precursor compounds for producing a layer which contains a precious metal, in particular platinum, or a metal layer consisting of a precious metal, in particular platinum, in particular on at least one surface of a substrate. The invention additionally relates to a substrate, in particular a substrate which can be obtained according to such a method. The invention also relates to a crosslinkable silicon composition comprising at least one compound with aliphatic carbon-carbon multi-bonds, at least one compound with Si-bonded hydrogen atoms, and at least one platinum (IV) complex of the aforementioned type. The invention also relates to novel alkali metal organo-dihydroazulenyls which can be used to produce metal complexes, in particular of the aforementioned type.
