On November 3, 2021, the 2020 National Science and Technology Award conference was held in the Great Hall of the people. "Chelation chemistry of carbon chain and metal", the scientific research achievement of Haiping Xia 's team won the second prize of the National Natural Science Award. Haiping Xia and Hong Zhang attended the award ceremony in Beijing.

Our work was selected as one of 2013 Top 10 Scientific and Technological Achievements from Chinese Universities.

Prof. Haiping Xia received the prestigious Huang Yao-zeng Organometallic Chemistry Award of the Chinese Chemical Society in 2016 in the 19th National Conference on Organometallic Chemistry on China.

Author profile of Prof. Xia was published in Angew. Chem. Int. Ed., for our group has recently published the 10th article in Angew. Chem. Int. Ed. in the last 10 years since 2004.

Aromaticity, one of the most fundamental concepts in organic chemistry, provides intrinsic stabilisation for cyclic compounds as a result of the delocalisation of π electrons. Currently, aromatic compounds (e.g., benzene, benzene derivatives, porphyrins, fullerenes, carbon nanotubes and graphene) have been applied in almost every field, including chemical engineering, biomedicine, materials science, energy science and environmental science.

We reported the first case of high-tensile and anti-aromatic carbon dragon compound, the metal bridgehead indene. The results were published online in the Journal of the American Chemical Society under the title "Isolation, Reactivity, and Tunable Properties of a Strained Antiaromatic Osmacycle." Am. Chem. Soc.

We report the preparation method of the first Craig anti-aromatic species, and analyze the nature and driving force of antiaromatic species combined with theoretical calculation system. Thus, two centuries after the discovery of the first aromatic species (naphthalene), the puzzle of the π aromatic system was perfected . The results were published online in the Proceedings of the National Academy of Sciences under the title "Synthesis and Characterization of Craig-type Antiaromatic Species with [4n + 2] π Electrons"

We have made another important advance in the field of "carbon dragon chemistry": we proposed a strategy based on π- and σ-aromatic relay drive, realizing the first metal heterocyclic butadiene to metal heterocyclic propylene ring shrinkage reaction. The results were published online in Nature Synthesis under the title "Ring Contraction of Metallacyclobutadiene to Metallacyclopropene Driven by π- and σ-Aromaticity Relay"

We synthesized a "carbon dragon complex" with an absorption spectrum of NIR-II (Near Infrared Region II). The results were published online in Angew under the title "Condensed Osmaquinolines with NIR-II Absorption Synthesized by Aryl C-H Annulation and Aromatization". Chem., Int. Ed

We describe a heterometallic [Os-Cu] complex with the characteristics of bimetallics, metallaaromatics, and pincer complexes. This complex serves as a highly effective catalyst for selective amino- and oxyselenation of unactivated alkenes. More than 80 examples including challenging substrates of unsymmetric aliphatic alkenes and amine-based nucleophiles in such reactions are provided.
