摘要：
In this work, we report a novel octa-nuclear uranyl (U8) motif [(UO2)(8)O-4(mu(3)-OH)(2)(mu(2)-OH)(2)](4+) embedded in a uranyl-oxalate coordination polymer (compound 1) based on a U-shaped linker with extra-long xylylene chains for stabilizing the resulting high-nuclear motif through additional cross-linking connectivity. A comparison with dimeric and monomeric uranyl compounds obtained at different pH value from the same hydrothermal system reveals that, solution pH plays a vital role in formation of this octa-nuclear uranyl motif by promoting hydrolysis of uranyl source. Since high similarity of eight uranium centers in this nearly planar U8 motif here, overlapping and broadening of signals in fluorescence, infra-red (IR) and Raman spectra can be found.

摘要：
A simple and clean protocol for the synthesis of various alkyl and (hetero)aryl S-thiocarbamates was established. The usage of in situ generated hydroxide as both an oxygen source and hydrogen source as well as biomass-derived 2-methyltetrahydrofuran as a green reaction medium, the avoidance of phosphorus-containing reductant, and the generation of harmless water and nitrogen as the side-products have given the present method atom-economy and environmental friendliness.

摘要：
An eco-friendly and economical route for the oxidation of 5-hydroxymethylfurfural (HMF) to 2,5-furandicarboxylic acid (FDCA) with atmospheric dioxygen as the sole oxidant under acid-, base-, metal-, and external initiator-free conditions in minimal solvent was reported. In the present reaction, the 1,2-diethoxyethylane has a dual role: reaction medium and free-radical initiator. The FDCA easily crystallizes during the reaction and was simple purified via recrystallization to provide the pure FDCA.

摘要：
An eco-friendly protocol for the synthesis of various 2-sulfonyl quinolines/pyridines through sulfonylation of heteroaromatic N-oxides with sodium sulfinates in water at ambient temperature under metal- and oxidant-free conditions has been developed. The mild reaction conditions, high reaction efficiency, operational simplicity, short reaction time and remarkable functional-group compatibility make the developed protocol very attractive for the preparation of 2-sulfonyl N-heteroaromatic compounds.

摘要：
Herein we summarized some clean preparation examples to emphasize the concept of dual roles design (or named as "two birds one stone strategy") in green and sustainable chemistry. In those examples, the reactants and/or solvent play dual roles rendering a cleaner organic preparation process. Consequently, both the chemical waste and manufacturing cost could be reduced.
