Benzylation of alcohols with benzyl (Z)-2,2,2-trifluoro-N-(2-alkynylphenyl)acetimidates 5a-f in the presence of a cationic gold(I) catalyst was investigated. Reagent 5f was the most effective, affording benzyl ethers in good yields. Our results indicate that these gold(I)-activated imidates are effective leaving groups.

阳离子金（I）催化剂对亚氨酸酯的分子内活化：一种新的醇苄基化反应

研究了在阳离子金（I）催化剂存在下，醇与苄基（Z）-2,2,2,2-三氟-N-（2-炔基苯基）乙亚胺酸酯5a-f的苯甲酸酯化反应。试剂5f是最有效的，以高收率提供了苄基醚。我们的结果表明，这些金（I）活化的酰亚胺是有效的离去基团。
