Novel 2-chalcogen- or 2,6-dichalcogen-BODIPY derivatives were synthesized by a Pd-catalyzed C-heteroatom Stille cross-coupling reaction, overcoming the limitations of SNAr.
通过Pd催化的C-杂原子Stille交叉偶联反应合成了新型的2-硫属元素或2,6-二卤代-BODIPY衍生物,克服了S N Ar的局限性。

Sn and 125Te NMR spectroscopies reveal that methyl, primary and secondary alkyl radicals, generated by reaction of phenyltelluroalkanes 4, 6, 7 with tributyltin hydride (benzene, AIBN initiator), are capable of displacing tributylstannyl radicals from (4-fluorophenyltelluro)tributylstannane to afford the 4-fluorophenyltelluroalkanes 3, 8, 9.
