Benzenetellurinyl acetate or trifluoroacetate in combination with ethyl carbamate effected aminotellurinylation of olefins in chloroform under reflux in the presence of boron trifluoride etherate to give ethyl [(2-phenyltelluro)alkyl]carbamates in high yields after reduction with hydrazine hydrate. This reaction was extended to cyclofunctionalization of olefinic carbamates into nitrogen heterocycles.
乙酸苯碲酯或三氟乙酸酯与氨基甲酸乙酯组合,在三氟化硼乙醚存在下,在回流下,在氯仿中进行烯烃的氨基碲酰化,在用水合肼还原后,以高收率得到[(2-苯基碲)烷基]氨基甲酸乙酯。该反应扩展到烯属氨基甲酸酯环官能化成氮杂环。
