The carbonylation of the iodides 2a-c and 12a-b in benzyl alcohol with carbon monoxide affords the corresponding benzyl esters 3a-c and 13a-b in good yields. It is shown that 3a can be easily and selectively cleaved to the acid 4a by catalytic hydrogenation. The acid is converted to an ester, 7a, and an amide, 6a.
碘化物2a-c和12a-b在苄醇中用一氧化碳进行羰基化,得到相应的苄基酯3a-c和13a-b,收率很高。结果表明,通过催化氢化可以容易地和选择性地将3a裂解成酸4a。酸转化为酯7a和酰胺6a。
