This study aimed to provide a reference for the practical use of forchlorfenuron (CPPU) in improvement fruit set and quality (especially size) litchi (Litchi chinensis Sonn.). CPPU at 5 mg/L was sprayed clusters ‘Feizixiao’ 2, 4, 6 8 weeks after female bloom (WAFB) 2017 6, 8, 9 or 10 WAFB 2018, with spraying water as control. The treatments were all effective suppressing abscission, resulting h...

A practical method to synthesize sulfinate esters from aryl iodides is disclosed. Direct oxidation of thioesters prepared by copper-catalyzed C–S formation realized the efficient synthesis sulfinate...

Going to the source: The trifluoromethylation of aryl/heteroaryl iodides has been demonstrated using a flow system, thus enabling a rapid rate of reaction. A broad spectrum of trifluoromethylated compounds was prepared in good to excellent yields using CF3 CO2 K as the trifluoromethyl source. The process has the advantage of short reaction times and uses convenient [CF3 ] sources.

We disclose herein the perfluoroalkylation of alkenes catalyzed by trifluoroethoxy-coated zinc phthalocyanine under irradiation of visible light. Perfluoroalkyl iodides were nicely incorporated into unsaturated substrates, including alkyne, to provide perfluoroalkyl and iodide adducts in moderate to good yields. Trifluoromethylation is also possible by trifluoromethyl iodide under the same reac...
