摘要:
To provide a method of rapid methylation of alkenes, which is applicable to the preparation of a PET tracer and which enables alkenes to be methylated through cross coupling between SP 2 (alkenyl) and SP 3 (alkyl) carbon atoms rapidly and in a high yield. Methyl iodide and an alkenyltrialkylstannane are subjected to cross coupling in an aprotic polar solvent in the presence of a palladium complex having a valence of 0, a phosphine ligand, a cuprous halide, and a carbonate and/or alkali metal fluoride.
