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 …

In all previously reported metallacycloprop-1-ene or η2-vinyl complexes, the metal center
bears only one vinyl moiety. We have now successfully synthesized and structurally …

Metal-containing polymers have drawn considerable interest because of their unexpected
and fantastic properties, and can be applied for preparing functional hydrogels. However …

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

The selective photoreactions under mild conditions play an important role in synthetic
chemistry. Herein, efficient and mild protocols for switching the photoreactions of Ir (III) …

Ring contraction of metallacyclobutadiene to metallacyclopropene is rare because of the
increasing strain from a four-membered ring to a three-membered one. Here we …

The feasibility of coupling of two carbene ligands of biscarbene complexes LnM (= CR2) 2 to
form alkene complexes LnM (η2-R2C= CR2) was predicted theoretically as early as 1982 …

The postcoordinated interligand-coupling strategy provides a useful and complementary
protocol for synthesizing polydentate ligands. Herein, diastereoselective photoreactions of Λ …

Reactions of terminal alkynes (alkyl− C≡ CH) and internal alkynes with rhenium (III)
phosphine complex ReCl3 (PMePh2) 3 were studied, producing cationic mononuclear bi …

Main observation and conclusion The diastereoselective photoreactions of Ir (III)‐amine and
Ir (III)‐diamine complexes are observed in the presence of O2. The Ʌ‐[Ir (pq) 2 (R …
