Novel and Direct Nucleophilic Sulfenylation and Thiocyanation of Phenol Ethers Using a Hypervalent Iodine(III) Reagent
摘要:
Novel and direct nucleophilic sulfenylation and thiocyanation of phenol ethers and related compounds (1) with the hypervalent iodine reagent, phenyliodine(III) bis(trifluoroacetate) (PIFA) have been developed. The reaction proceeded smoothly in 1,1,1,3,3,3-hexafluoro-2-propanol ((CF3)(2)-CHOH), a poorly nucleophilic and polar solvent. Various unsymmetrical diaryl sulfides and aryl thiocyanates, which could be applicable to the synthesis of various types of sulfur-containing aromatic compounds, were prepared in good yields. These reactions could be performed under mild conditions without heating or the use of strong Lewis acid catalysts.
