alkyl allyl carbonates with a phosphine-free palladium catalyst in acetonltrile affords ketones or aldehydes in high yields. This new method of oxidation of alcohols via allyl carbonates can be applied to various alcohols except simple primary alcohols. The reaction proceeds under neutral conditions and hence various acid- or base-sensitive functional groups are not affected during the reaction. Ruthenium
用无膦的钯催化剂在乙腈中处理碳酸烷基烯丙酯可高产率得到酮或醛。这种经由碳酸烯丙酯氧化醇的新方法可应用于除简单伯醇之外的各种醇。反应在中性条件下进行,因此在反应过程中不影响各种对酸或碱敏感的官能团。氢化钌配合物也是一种有效的催化剂。仲或烯丙基醇的直接脱氢反应是通过钌络合物的催化作用与碳酸烯丙酯反应进行的。1,4-二醇和1,5-二醇与过量的碳酸烯丙酯转化为内酯。
