2,2’-bipyridyl calcium complex based on a tridentate ligand [CH3C(N-2,6-iPr2C6H3)CHC(CH3)NCH2CH2N(CH3)2]Ca(bipy)(THF) (1) was prepared by reduction of {[CH3C(N-2,6-iPr2C6H3)CHC(CH3)NCH2CH2N(CH3)2]CaI(THF)}2 with potassium graphite in the presence of 2,2’-bipyridine (bipy). Complex 1 is a good...
Herein, a visible light‐mediated multicomponent radical cross‐coupling reaction of [1.1.1]propellane with N‐heterocycles and disulfides is described. The mild conditions enabled the installation of the BCP motif in a wide variety of compounds in the absence of photocatalyst, additive and metal catalyst, with excellent functional group tolerance, This methodology opens a approach for the synthesis of potentially bioactive 1‐arylthiol‐3‐heteroaryl bicyclo[1.1.1]pentanes in moderate to good yield.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
