应用
3-Bromo-4-fluorotoluene was employed as starting reagent in the synthesis of [4-fluoro-3-(trimethylsilyl)benzyl]guanidine. It was also employed as benzyne precursor in the synthesis of 6-methyl-1,2,3,4-tetrahydro-2,3-(benzylidenedioxy)-1,4-ethenonapthalene.

With 3-bromo-4-fluorotoluene as starting material, [4-fluoro-3-(trimethylsilyl)benzyl]guanidine was prepared in five steps in 1.5% overall yield. Radioiodination of this silicon precursor using N-chlorosuccinimide in trifluoroacetic acid at room temperature for 5 min gave (4-fluoro-3-[131I]-iodobenzyl)guanidine ([131I]FIBG) in 50-60% radiochemical yield.
