affords cyclic carbonates. The oxidative carbonylation of diols proceeds under mild conditions, requiring only 1 atm of carbon monoxide, and produces cyclic carbonates in moderate to good yields. Both 1,2- and 1,3-diols can be carbonylated using (neocuproine)Pd(OAc)2 and sodium dichloroisocyanuric acid, which serves as a competent oxidant and base for this system, to yield 5- and 6-membered cyclic carbonates
以N-氯代琥珀酰亚胺为底物,由(新癸胺)乙酸钯(II)(新丙氨酸= 2,9-二甲基-1,10-菲咯啉)或乙酸钯(II)/(-)-黄嘌呤催化1,2-二醇的烷氧基羰基化反应。氧化剂提供环状碳酸酯。二醇的氧化羰基化反应在温和的条件下进行,仅需1 atm一氧化碳,并以中等至良好的收率生产环状碳酸酯。1,2-二醇和1,3-二醇都可以使用(新oc碱)Pd(OAc)2和二氯异氰尿酸钠进行羰基化反应生成该5元和6元环状碳酸酯,后者是该体系的有效氧化剂和碱。 。
