Iminoacyl Functions Linked to Chalcogens Other Than Oxygen

摘要: This chapter reviews the transformations that have been used to prepare imidoylsulfur, -selenium, and -tellurium derivatives with particular emphasis on newer methods published since 1993. Thioimidic esters, which are often called thioimidates, most common class of compounds this type. A variety for synthesis thioimidates described, including alkylation thioamides alkylating reagents, addition thiols nitriles or activated imidoyl derivatives, carbon nucleophiles isothiocyanates followed by subsequent S-alkylation. Selenoimidates prepared analogous those corresponding sulfur compounds. Some recent advances in preparation selenoimidates involve generation coupling radicals diaryl diselenides. Recent developments radical-mediated group—transfer imidoylation organotellurium isonitriles has greatly increased reported examples telluroimidates these covered together some established methods. Methods preparing chalcogen where is attached a heteroatom also reviewed. The classes include sulfenates, disulfides diselenides, imidoylthiophosphorus imidoylthiometalloid imidoylthiometal derivatives.
