摘要:
What is described is a process for preparing organic compounds of the general formula (I) R—R′ (I) by converting a corresponding compound of the general formula (II) R—X (II) in which X is fluorine, chlorine, bromine or iodine to an organomagnesium compound of the general formula (III) [M+]n[RmMgXkY1] (III) wherein compounds of the formula (III) are reacted with a compound of the general formula (IV) characterized in that the reaction of (III) with (IV) is performed in the presence of a) catalytic amounts of an iron compound, based on the compound of the general formula (II), and optionally in the presence of b) a nitrogen-, oxygen- and/or phosphorus-containing additive in a catalytic or stoichiometric amount, based on the compound of the general formula (II).

摘要:
This invention relates to a process for preparing functionalized aryl, heteroaryl, cycloalkenyl, or alkenyl compounds, by a transition-metal-catalyzed cross-coupling reaction of a substituted or unsubstituted aryl-X, heteroaryl-X, cycloalkenyl-X or alkenyl-X compound with an alkyl, alkenyl, cycloalkyl or cycloalkenyl halide, where X is a halide, diazonium, tosylate (p-toluenesulphonate), mesylate (methanesulphonate) or triflate (trifluoromethanesulphonate) leaving group.
摘要:
A process for preparing organic compounds of the general formula (I) R—R′ (I), where R is a substituted or unsubstituted aromatic, heteroaromatic, cycloalkenylic or alkenylic radical and R′ is a substituted or unsubstituted alkylic, alkenylic, cycloalkylic or cycloalkenylic radical, by reacting a corresponding compound of the general formula (II) R—X (II), where X is chlorine, bromine, iodine, diazonium, mesylate (methanesulphonate), tosylate (p-toluenesulphonate) or triflate (trifluorosutphonate) and R is as defined for formula (I), with a corresponding compound of the general formula (III) R′—Y (III), where Y is chlorine, bromine or iodine and R′ is as defined for formula (I), wherein the reaction is carried out in the presence of a) stoichiometric amounts of elemental magnesium, based on the compound of the general formula (II), and b) catalytic amounts of a transition metal compound, based on the compound of the general formula (II), and, if appropriate, c) in the presence of a nitrogen-, oxygen- and/or phosphorus-containing additive in a catalytic or stoichiometric amount, based on the compound of the general formula (II), is described. It is particularly advantageous that the process of the invention is carried out as a one-pot reaction and the organomagnesium compound (Grignard compound) formed in situ as intermediate is not isolated.
