Method for allylating and vinylating aryl, heteroaryl, alkyl, and alkene halogenides using transition metal catalysis

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 whichX is fluorine, chlorine, bromine or iodine to an organomagnesium compound of the general formula (III)[M⁺]_n[R_mMgX_kY₁]  (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 ofa) catalytic amounts of an iron compound, based on the compound of the general formula (II), and optionally in the presence ofb) a nitrogen-, oxygen- and/or phosphorus-containing additive in a catalytic or stoichiometric amount, based on the compound of the general formula (II).
