“…Recently, the Gaunt research team prepared heteroaryl-uracil-iodonium(III) triflates using m CPBA ( m -chloroperbenzoic acid) and triflic acid as an oxidant and counterion, respectively, and then utilized these synthesized salts for organocatalytic arylation of aldehydes [20]. However, the isolation and application of uracil-iodonium(III) salts remained mostly limited to treating triflate ( − OTf) salts [18,19,20,21,22], and the relationship between their stability and the structural feature of uracil-iodonium(III) salts has still not been sufficiently explored. This is likely because of their hygroscopic characteristics causing gradual decomposition, as claimed in previous studies [20].…”
