Aromatic chloroosmacyclopentatrienes

open access: yesNational Science Review, 2022
ABSTRACT Aromatic metallacycles are of considerable current interest. Reported aromatic metallacycles are mainly those with carbon, nitrogen, oxygen and sulfur. In this work, we report the synthesis and characterization of aromatic chloroosmacyclopentatrienes, which represent the first structurally confirmed metallaaromatic with a ...

Hydrogenated polycyclic aromatic hydrocarbons: isomerism and aromaticity

open access: yesPhysical Chemistry Chemical Physics, 2020
A simple model based on adjacency matrices is introduced to study the stability of hydrogenated polycyclic aromatic hydrocarbons. Aromaticity governs their relative stability having the most stable isomers the higher number of non-hydrogenated rings.

Chemical stability of carbon pool in peatlands dominated by different plant types in Jilin province (China) and its potential influencing factors

open access: yesFrontiers in Ecology and Evolution, 2023
IntroductionThe peat carbon pool stores 30% of the total global soil carbon accounting for 3–4% of the global land surface. The stability of the peatland carbon pool is a key factor affecting global carbon cycling that is seriously disturbed by climate ...
