Low-valent early transition metals are often intrinsically highly reactive as a result of their
strong propensity toward oxidation to more stable high-valent states. Harnessing these …

This review article summarizes recent progress in the synthesis and optoelectronic
properties of conjugated materials containing heavy main group elements from Group 13 …

Metallacyclopentadienes, which possess two M–C (sp2) bonds and feature the structure of
M (CR1CR2–CR3CR4), are an important class of five-membered metallacycles. They are …

A divergent synthetic strategy allowed access to several members of a new class of
helicenes, the “expanded helicenes”, which are composed of alternating linearly and …

Expanded helicenes are large, structurally flexible π-frameworks that can be viewed as
building blocks for more complex chiral nanocarbons. Here we report a gram-scale …

Benzo [b] heteroles containing heteroatoms other than nitrogen and oxygen have received
considerable attention for their potential applications in materials science. This poses an …

Cp2TiCl2-catalyzed regioselective hydrocarboxylation of alkenes with CO2 to give
carboxylic acids in high yields has been developed in the presence of i PrMgCl. The …

Organoarsenic chemistry was actively studied until the middle of 20th century. Although
various properties of organoarsenic compounds have been computationally predicted, for …

A synthesis of tellurium-embedded π-extended aromatics from tellurium powder and readily
available cyclic diaryliodonium salts has been developed. The versatility of this method has …

As the key intermediates in metal-catalyzed [2+ 2+ 2] cycloaddition reactions of three
alkynes, main-group and transition-metal metallacycloheptatrienes have been studied for …
