    摘要: It is intended to provide a method of rapid methylation of an aromatic compound or an alkenyl compound, which is capable of obtaining an aromatic compound or an alkenyl compound labeled with a methyl group or a fluoromethyl group under a mild condition rapidly in high yield using an organic boron compound whose toxicity is not so high as a substrate; a kit for preparing a PET tracer to be used in the same, and a method of producing a PET tracer using the same. In an aprotic polar solvent, methyl iodide or X—CH2F (wherein X is a functional group which can be easily released as an anion), an organic boron compound in which an aromatic ring or an alkenyl group is attached to boron are subjected to cross-coupling in the presence of a palladium(0) complex, a phosphine ligand, and a base.

    摘要: A method of rapid methylation of an aromatic compound or an alkenyl compound, which is capable of obtaining an aromatic compound or an alkenyl compound labeled with a methyl group or a fluoromethyl group under a mild condition rapidly in high yield using an organic boron compound whose toxicity is not so high as a substrate. A kit for preparing a PET tracer and a method of producing a PET tracer can be practiced using the rapid methylation method. In an aprotic polar solvent, methyl iodide or X—CH2F (wherein X is a functional group which can be easily released as an anion), and an organic boron compound in which an aromatic ring or an alkenyl group is attached to boron are subjected to cross-coupling in the presence of a palladium(0) complex, a phosphine ligand, and a base.

    摘要: Provided are: a method for rapid fluoromethylation, by which a fluoromethyl group can be easily bonded to an aromatic-ring carbon of an aromatic compound with little generation of by-products; and a process for preparation of a PET tracer using the same. The method is characterized by cross-coupling an organoboron compound in which an aromatic ring is bonded to a boron atom with FCX2Br (wherein X is ordinary hydrogen or heavy hydrogen) in a solvent obtained by adding water to an aprotic polar solvent, in the presence of a palladium complex, a phosphine ligand, and a base.
