8-Methoxyquinoline based turn-on metal fluoroionophores
Zhang, Han,Wang, Qiang-Li,Jiang, Yun-Bao
, p. 3959 - 3962 (2007)
Novel turn-on fluoroionophores 2 and 3 based on highly fluorescent 8-methoxyquinoline were developed in which a sequential singlet-singlet energy transfer, ISC, and triplet-triplet energy transfer occurred leading to a fluorescence 'off' state. They showe
Dichloroacetophenone Derivatives: A Class of Bioconjugation Reagents for Disulfide Bridging

, p. 8193 - 8197 (2020)
A mild and biocompatible method for the construction of disulfide bridging in peptides using dichloroacetophenone derivatives is developed. This method is highly selective (chemo, diastereo, regio, etc.) and atom economic and works under biocompatible reaction conditions (metal-free, water, pH 7, rt, etc.).

Transition-metal- and phosphorus-free electrophilic trifluoromethylthiolation of indoles with sodium trifluoromethanesulfinates in ionic liquids
Wang, Fei,Lu, Guo-Ping,Lin, Yamei
, (2021/04/12)
An acid-promoted protocol has been developed to achieve the transition-metal- and phosphorus-free electrophilic trifluoromethylthiolation of indoles using sodium trifluoromethanesulfinates in an imidazolium-based ionic liquid ([Hmim]Br). [Hmim]Br not only acts as a recyclable solvent, but also as the reductant in this transformation. The advantages of this chemistry include simple operation, use of a recyclable solvent, avoidance of transition-metal and phosphorus, and gram-scale synthesis.
Solvent-free preparation of α,α-dichloroketones with sulfuryl chloride

An efficient and facile method is reported for the synthesis of a series of α,α-dichloroketones. The direct dichlorination of methyl ketones and 1,3-dicarbonyls using an excess amount of sulfuryl chloride affords the corresponding gem-dichloro compounds in moderate to excellent yields. Moreover, the protocol features high yields, broad substrate scope, and simple reaction conditions without using any catalysts and solvents.
