The C–H acyloxylation of polycyclicaromatichydrocarbons (PAHs) is described. This reaction constructs aryl acyloxylate scaffolds from PAHs with equimolar hypervalent iodine compounds under mild reaction conditions. Interestingly, the blue light irradiation accelerated this transformation. Additionally, the synthesis of structurally new symmetric and unsymmetric diaroyloxylated fluoranthenes was accomplished
formula R4N[I(O2CAr)2] is reported. These compounds are air‐ and moisture‐stable iodine(I) reagents, which were characterized including X‐ray analysis. They represent conceptually new iodine(I) reagents with anions as stabilizers. These compounds display the expected performance as electrophilic reagents upon interaction with electron‐rich substrates. The performance of these compounds in a total of
报道了通式为R 4 N [I(O 2 CAr)2 ]的亲电碘试剂的一般合成,分离和表征。这些化合物是空气和水分稳定的碘(I)试剂,其特征包括X射线分析。从概念上讲,它们代表带有阴离子作为稳定剂的新碘(I)试剂。这些化合物在与富电子底物相互作用时作为亲电子试剂显示出预期的性能。研究了这些化合物在烯烃的邻位碘加氧的总共47个不同反应中的性能,并揭示了该试剂的一些关键特征。
