Sulfamoyl azides are readily generated from secondary amines and a novel sulfonyl azide transfer agent, 2,3-dimethyl-1H-imidazolium triflate. They react with alkynes in the presence of a CuTC catalyst forming 1-sulfamoyl-1,2,3-triazoles. The latter are shelf-stable progenitors of rhodium azavinyl carbenes, versatile reactive intermediates that, among other reactions, readily and asymmetrically add
磺酰基叠氮化物很容易由仲胺和新型磺酰叠氮化物转移剂 2,3-二甲基-1 H-咪唑鎓三氟甲磺酸盐生成。它们在 CuTC 催化剂存在下与炔烃反应形成 1-氨磺酰基-1,2,3-三唑。后者是铑氮杂乙烯基卡宾的货架稳定前体,是多功能的反应中间体,在其他反应中,很容易和不对称地添加到烯烃中。
