Three coordination polymers (CPs) were synthesized by CdII, fluorescent 9,10-di(4-pyridyl)anthracene (dpa), and cyclohexane-1,4-dicarboxylic acid (H2cda), which are [Cd2(dpa)2(cda)Cl2]n (1), [Cd(dpa)2(cda)]n (2) and [Cd(dpa)(cda)(H2O)]n (3). Both 1 and 2 are fluorescent...

In recent years, remarkable advances on remote C(sp3)-H bond or aldehydic C(sp2)-H functionalizations enabled by intermolecular radical addition to C=C bond/(1,n)-HAT tandem sequences have been witnessed, which provided an efficient...

A copper-catalyzed alkene-trifluoromethylation-triggered nitrile insertion/remote functionalization relay process has been achieved, in which “interrupted” remote 1,n-difunctionalizations of alkenes with nitrile insertion can deliver iminyl radical intermediates instead of C-based radicals, followed by subsequent 1,n-HAT to furnish corresponding remote functionalization. This relay protocol enables a straightforward approach to streamline the assembly of structurally diverse trifluoromethylated azaheterocycles.

A copper-catalyzed difluoroalkylation of an alkene/nitrile insertion/cyclization tandem sequence of N-cyanamide alkene was described, which provided a convenient synthetic approach for accessing difluorinated bicyclic amidines bearing imine moieties in a sustainable fashion. This protocol is characterized by high yields, a broad substrate scope, and good functional group compatibility. In addition, the desired product can be readily converted into other valuable functionalized fluorinated aza-heterocycles.B icyclic amidine moieties (partially saturated pyrrolo [2,3b]pyridine or 1,8-naphthyridine) have been found in a series of natural alkaloids such as perophoramidine, communesins, and dehydronitraramine, 1a−d bioactive molecules [(S)-Blebbistatin], 1e amidine bases, acceptors of molecular recognitions etc. (Figure 1). 1f−h However, a few synthetic Letter pubs.acs.org/OrgLett

An electrochemical three-component transformation between N-cyanamide alkene, Na2S2O5 and sulfonyl hydrazide was described, in which various sulfonylated fused sultams were prepared in a sustainable and modular fashion. In this process,...
