摘 要:1 Introduction Heteroatom-stabilized carbenium ions have been widely recognized as potential electrophilic reagents.However,in contrast with the extensive works on thionium ion series,the highly labile character of selenoxide functionalities has caused serious limitation in the synthetic use in spite of their wide potentiality as synthetic equivalents of electrophilic selonium ions.In this paper,novel generation of selonium ions and the synthetic uses of the species for Pummerer-typeα-functionalization and for cycloaddition by using the novel dienophilic behavior ofπ-conjugated selonium cations.
关 键 词:selenoxide alkenyl selenoxide Pummerer reaction a-allylation a-azidation Diels-Alder reaction seloniumion
