应用广泛的一种化合物——1-(三氟甲基)-1,2-苯碘酰-3(1H)-酮,是有机合成及医药研发中的重要中间体,在实验室有机合成和化工医药合成过程中发挥着重要作用。
The development of new methodologies for an efficient introduction of CF3 groups into complex molecules constitutes one of the most challenging tasks of modern organic chemistry. Recently, we reported the access to a new class of electrophilic CF3-transfer reagents based on hypervalent iodine. The versatile application of these reagents to C-centred nucleophiles, such as ?-keto esters, silyl enol ethers and ?-nitro esters, as well as to thiols and primary and secondary phosphines is described. Experiments with phenols afforded corresponding trifluomethylethers in very low yields.
