| Outline of Final Research Achievements |
The selective monocyclization of Cationic Lithium Endohedral Fullerene with dibromide in the presence of manganese powder has been studied. The selective cyclotrimerization of 5-bromothiazole through sequential C-H bond functionalization has been developed in the presence of Pd(II) catalyst toward synthesis of novel star-shaped π-extended benzotristhiazoles. The biphenyl-tethered ortho-alkynylanilines undergo the tandem cyclization through Pd(II)-catalyzed C-N/ortho-C-H bond cleavage to give the corresponding dibenzo[a,c]carbazoles effectively. A novel FeCl3-mediated oxidative spirocyclization for construction of a new class of dispirolinked π-conjugated molecules, dispiro[fluorene-9,5'-indeno[2,1-a]indene-10',9''fluorene]s (DSFIIFs), has been developed. A highly efficient single electron oxidative spirocyclization and 1,2-aryl migration tandem synthetic method for the construction of extended polyaromatic hydrocarbons (PAHs) has been developed.
