The bimetallic reagent Sn(II)/Cu(II) in [bmim]BF4 was efficiently used for the cleavage of diaryl diselenides and disulfides and reacts with a variety of organic substrates, such as organic halides, acid chlorides, and β-amino mesylates affording the diorganyl selenides and sulfides within very short reaction times, under mild conditions and with excellent yields, using BMIM-BF4 as a reusable solvent
[bmim] BF 4中的双金属试剂Sn(II)/ Cu(II)可有效地裂解二芳基二硒化物和二硫化物,并与多种有机底物反应,例如有机卤化物,酰氯和β-氨基甲磺酸酯使用BMIM-BF 4作为可重复使用的溶剂,可在非常短的反应时间内,在温和的条件下,以极好的收率提供二有机基硒化物和硫化物。
