酸性条件下多苯基取代环戊二烯的氧化扩环反应

Ring-Enlargement Oxidation of Polyphenyl Substituted Cyclopentadiene Promoted by Perchloric Acid

报道了空气 (或氧气 )存在的条件下 ,由高氯酸引发多苯基取代环戊二烯发生新颖的碳—碳键断裂扩环反应 ,在此反应中 ,氧原子插入到环戊二烯环中形成相应的六元环吡喃盐类化合物 .分别用红外光谱、核磁共振氢谱、碳谱。

novel ring-enlargement oxidation of polyphenyl substituted cyclopentadienes in air (or molecular oxygen) promoted by peruhloric acid was described, in which an oxygen atom was inserted into the cyclopentadiene-ring, forming a six-membered pyryburn salts. The structure of the resulting pyryliurn salts was confirmed by MIR, H-1 NMR, C-13 NMR, MS spectroscopies and elemental analyses.
