efficient and transition-metal-free multicomponent coupling reaction for the synthesis of aroyloxyl alkyl iodides. In the reaction among 2,4,6-triarylboroxines, THF, TMSCF3, LiOH, and NaI, five-component reactions could be precisely controlled by modulating CF3SO2Na, supplying one type of aroyloxyl alkyl iodides in moderate to high yields. The reaction exhibits good functional group tolerance and a wide substrate
在此,我们开发了一种高效且不含过渡金属的多组分偶联反应,用于合成芳酰氧基烷基碘。在2,4,6-三芳基环硼氧烷、THF、TMSCF 3 、LiOH和NaI的反应中,通过调节CF 3 SO 2 Na可以精确控制五组分反应,提供一种中高产率的芳酰氧基烷基碘. 该反应表现出良好的官能团耐受性和广泛的底物范围,可以很容易地转化为其他有用的化合物。该机制是在控制实验的基础上提出的
