Abstract: [Problem] To provide a preparation process by which an organic alkali metal compound is obtained in a high yield and a process for preparing an organic transition metal compound using the organic alkali metal compound. [Means to solve the problem] A process for preparing an organic alkali metal compound, which is characterized by adding a compound represented by the following formula (2) in the reaction of an active proton-containing compound represented by the following formula (1) with an alkali metal compound. RHp ??(1) In the formula (1), R is a hydrocarbon group or an amino group and may contain a halogen atom, a silicon atom, an oxygen atom or a nitrogen atom, H is an active proton, and p is the number of hydrogen atoms abstracted in the reaction with the alkali metal compound.

Abstract: The invention relates to a process for preparing Grignard compounds of the formula I. The invention additionally relates to compounds of the formula I and to polymer-bound compounds of the formula Ia. The invention further relates to the use of the process for preparing substance libraries and to the use of the compounds of the formulae I and Ia in chemical synthesis.

Abstract: A process for the manufacture of alkanes comprising a cross-metathesis reaction between at least one starting alkane (A) and one organometallic compound (B) fixed to an inorganic support and comprising a metal bonded to at least one hydrocarbon-comprising radical. The reaction leads to the formation of at least one other alkane (C) which is a higher or lower homologue of the starting alkane (A), by cleavage of the hydrocarbon-comprising radical with the metal of the organometallic compound (B) and recombination of the radical with at least one other radical originating from a cleavage of the starting alkane (A). The metal of the compound (B) preferably is selected from transition metals, lanthanides and actinides, and the hydrocarbon-comprising radical of the compound (B) preferably is selected from alkyl, alkylidene and alkylidyne radicals.

Abstract: Pentafluorophenyl Grignard reagents are reacted with a boron trihalide in a non-ethereal solvent such as toluene to produce a tetrakis pentafluorophenyl borate magnesium halide.
