Abstract: A metal-free radical 1,2-difunctionalization of activated alkenes with various silanes and tert-butyl nitrite is reported. The radical cascade occurs by light-promoted homolytic O-NO bond cleavage of tert-butyl nitrite and subsequent hydrogen atom abstraction by the…

Abstract: A visible-light photocatalytic aerobic oxidative lactonization of arene C(sp2)–H bonds proceeds in the presence of 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ) and tert-butyl nitrite (TBN). Under the optimized conditions, a range of 2-arylbenzoic acids is converted into the corresponding…

Abstract: ABSTRACT A multi-step catalyst-free synthesis of azo compounds by using n-butyl nitrite as a diazotization reagent and p-toluene sulfonic acid as a mild acidic agent in ethanol/water mixed solvent was investigated. In the combined one-pot…
