亲电二氟甲基试剂S⁃(二氟甲基)硫𬭩盐对1,1⁃偕二氰基烯烃的二氟甲基化: 二氟甲基取代全碳中心的有效构建

An efficient approach for difluoromethylation of dicyanoalkylidenes by electrophilic S-（difluoromethyl）sulfonium salt under organic base was described. A wide range of structurally and functionally diverse dicyanoalkylidenes was readily transferred into corresponding desirable difluoromethylated compounds bearing difluoromethylated all-carbon-substituted centers in good to excellent yields under standard reaction conditions.     

酞菁铁-聚苯胺型高分子吸波材料的合成及表征

以苯胺等为原料,合成了酞菁铁-聚苯胺新型高分子吸波材料,并用IR对其进行了表征。初步分析和确定了该聚合物的结构与微波吸收性能,在8.4GHz左右及9.3GHz以上吸波性能较好,吸收率达到80%以上。为合成新一代轻质、宽频、红外兼容的高分子微波吸收材料作了有益的探索。
