| Outline of Final Research Achievements |
The development of nanospace-controlled catalysis towards challenging molecular transformations, focusing on direct functionalization of saturated hydrocarbons, was carried out. Cationic gold(I) complexes with hollow-shaped triethynylphosphine ligands efficiently catalyzed intramolecular [2+2] cycloaddition of 1,9-enynes to afford cyclobutene-fused eight-membered carbocycles. For construction of precise catalytic environments, bulky P-alkynyl-substituted bisphosphine and PCP-pincer-type ligands were designed and synthesized. These polydentate ligands were applied to Pt(II)-catalyzed cycloisomerization of 1,8-enynes.
