Outline of Final Research Achievements

We succeeded in the synthesis of the new diphosphene having the P=P double-bond, which is expected to have the high electron-accepting character, and 1,1’-binaphthyl group with the axial chirality in both racemic and enantiomerically pure forms. Spectroscopic analyses, X-ray crystallographic analysis, and theoretical calculations revealed their structures, properties, and isomerization behavior among four stereoisomers. Furthermore, the corresponding diphosphene-gold(I) complex was isolated and utilized as a catalyst for the intramolecular hydroarylation reaction of aryl butynyl ether.
