The structural design and tuning of properties of metallaaromatics are crucial in materials
and energy science. Herein, we describe the rapid synthesis of tetracyclic metallaaromatics …

Comprehensive Summary Metallacyclopentadienes play a vital role in transition‐metal
mediated and catalyzed cycloaddition reactions of alkynes. Though versatile reactions of …

Strong intermolecular interactions usually facilitate charge transport, but impede
photoluminescence, therefore, the development of organic π‐conjugated materials that …

The first chlororuthenacyclopentatrienes have been realized by the reactions of RuCl2
(PPh3) 3 with o-phenyldiyne derivatives in the presence of excess HCl. The structures of the …

The Simmons–Smith reaction offers a direct route for conversion of an alkene into a
cyclopropane with a zinc carbenoid as the active intermediate. Zinc carbenoids, however …

Although the reaction chemistry of transition metallacyclopropenes has been well‐
established in the last decades, the reactivity of rare‐earth metallacyclopropenes remains …

Synthetic chemistry enables constructing molecular complexity using simple substrates
through simple processes. We disclose an unprecedented Al-atom transfer strategy for the …

Comprehensive Summary Starting from an organic multiyne, three steps are normally
needed for the preparation of non‐β‐phosphonium functionalized rhoda‐and irida …
