Carbonate anions resulting from reaction of primary or secondary alcohols with carbon dioxide, when added to methanesulfonic anhydride in cooled acetonitrile solution, yield methanesulfonyl carbonates, a new class of synthetic intermediate. Base-mediated reaction of the methanesulfonyl carbonates with alcohols, thiols, and amines yields carbonates, thiocarbonates, and carbamates, respectively. Overall
由伯醇或仲醇与二氧化碳反应生成的碳酸根阴离子,在冷却的乙腈溶液中加到甲磺酸酐中后,会产生甲磺酰碳酸酯,这是一类新的合成中间体。甲磺酰碳酸酯与醇,硫醇和胺的碱介导反应分别产生碳酸盐,硫代碳酸盐和氨基甲酸酯。这三个步骤的总产率从19%到42%不等。
