the chlorination of indene. An efficient chlorination of β-keto esters, 1,3-diketones, and alkenes was performed conveniently with concentrated HCl in the presence of PhIO, selectively giving α-chloro-β-keto esters, 2-chloro-1,3-diketones, and 1,2-dichloroalkanes, respectively. It was suggested that the chlorination took place with (dichloroiodo)benzene generated in situ. A selective anti-addition was
摘要 在PhIO存在下,用浓盐酸方便地对β-酮酸酯,1,3-二酮和烯烃进行有效氯化,选择性地得到α-氯-β-酮酸酯,2-氯-1,3-二酮,和1,2-二氯烷烃。建议用原位生成的(二氯碘代)苯进行氯化。在茚的氯化中观察到选择性的抗加成。 在PhIO存在下,用浓盐酸方便地对β-酮酸酯,1,3-二酮和烯烃进行有效氯化,选择性地得到α-氯-β-酮酸酯,2-氯-1,3-二酮,和1,2-二氯烷烃。建议用原位生成的(二氯碘代)苯进行氯化。在茚的氯化中观察到选择性的抗加成。
