Naphthalene formation by allylation of zirconaindenes in the ZnX2-Pd(PPh3)4 system
Zirconaindenes reacted with allyl halides in the presence of ZnX2 (X = Cl or Br) and a catalytic amount of Pd(Pph3)4 to give naphthalene derives in good yield.
MeOTf-catalyzed formal [4?+?2] annulations of styrene oxides with alkynes leading to polysubstituted naphthalenes through sequential electrophilic cyclization/ring expansion
MeOTf-catalyzed formal [4 + 2] annulation of styrene oxides with alkynes to afford polysubstituted naphthalenes has been realized, which undergoes sequential electrophilic cyclization/ring expansion. A range of substrates were tolerated in the formation of naphthalene derivatives with high regioselectivity in satisfactory yields. The reaction could also be carried out on gram scale.

Hydrazone-palladium catalyzed annulation of 1-allyl-2-bromobenzene derivatives with internal alkynes
Annulation of 1-allyl-2-bromobenzene derivatives with internal alkynes using a hydrazone-palladium catalyst system proceeded smoothly and gave the corresponding polysubstituted naphthalene derivatives in good to high yields.
Synthesis of substituted naphthalenes and carbazoles by the palladium-catalyzed annulation of internal alkynes
An efficient synthesis of highly substituted naphthalenes has been developed by the palladium-catalyzed annulation of a variety of internal alkynes, in which two new carbon-carbon bonds are formed in a single step under relatively mild reaction conditions

Photosensitized Electron-Transfer-Induced Reactions of Some Cyclopropene Derivatives
The 9,10-dicyanoanthracene-sensitized rearrangement of several 3-phenyl-substituted cyclopropenes to indenes in acetonitrile has been studied. When an unsymmetrically 1-phenyl-2-methyl-substituted cyclopropene was used, the major indene obtained correspon
