Abstract
The present invention relates to a process for preparing highly pure tris-ortho-metalated organometallic compounds and to pure organometallic compounds of this type, especially compounds of the d8 metals, which may find use as coloring components in the near future as active components (=functional materials) in a series of different types of applications which can be classified within the electronics industry in the widest sense.
Claims16
A process for forming carbon-metal bonds by ortho-metalation from a mixture of one or more organic compounds containing at least one C—H bond and at least one metal compound in a melt, suspension, dispersion, solution or in a supercritical medium, characterized in that microwave radiation acts on the mixture and that the reaction mixture is heated to at least 40° C.
