Molecular recognition and self-assembly are often mediated by intermolecular forces involving aromatic π-systems. Despite the ubiquity of such interactions in biological systems design functional materials, elusive nature π interaction results that they have been seldom used as a element for promoting challenging chemical reactions. Described here is well-engineered catalytic system into which non-covalent directly incorporated. Enabled lone pair-π π-π stacking operating collectively,...
Deconstructive alkynylation of an unstrained ketone catalyzed by organic photocatalyst under blue light irradiation is reported for the first time. A broad substrate scope with up to 63 examples, excellent functional group tolerance, and gram scale reaction demonstrated practicality this novel method. The dihydroquinazolinone derivative trifluoroacetophenone had been proved have potential as a trifluoromethylation reagent after working well various alkynyl bromides.
Abstract The catalytic conversion of CO 2 into valuable chemicals using metalized covalent organic frameworks (COFs) as catalysts is a promising method for reducing atmospheric levels. Herein, aldehyde‐amine COF (TAPT‐Tp) at room temperature and pressure their metallized results synthesized, Ni‐TAPT‐Tp Ti‐TAPT‐Tp. photocatalytic indicate that the to reduction rate 6182.5 µmol g −1 h Ni‐TAPT‐Tp, but only 1615.4 Density functional theory (DFT) simulations further demonstrate intermediates * ,...
Abstract The mechanistic uniqueness and versatility of borrowing hydrogen catalysis provides an opportunity to investigate the controllability a cascade reaction, more importantly, realize either one or both chiral recognition induction simultaneously. Here we report that, in starting from racemic allylic alcohols, enantiomers could be kinetically resolved, while other enantiomer purposely converted various targeted products, including α,β‐unsaturated ketones, β‐functionalized ketones...
Abstract The concept of odd-electron σ–bond was first proposed by Linus Pauling. Species containing such a bond have been recognized as important intermediates encountered in many fields. A number radicals with one-electron or three-electron σ-bond isolated, however, no example diradical based σ-bonds has reported. So far all stable diradicals are on two s / p -localized π -delocalized unpaired electrons (radicals). Here, we report dication that is Se∴Se σ–bonds. In contrast, the sulfur...
One-electron oxidation of 1,3-digerma-2,4-dipnictacyclobutadiene [LHGeE]2 (LH = CH[CHNDipp]2, dipp 2,6-iPr2C6H3; 1: E P; 2: As) with Ag[Al(ORF)4] (RF C(CF3)3) afforded the stable radical cation salts 1˙+·[Al(ORF)4]- and 2˙+·[Al(ORF)4]-, respectively. The have been fully characterized, in conjunction theoretical calculations. EPR spectroscopic studies DFT calculations reveal that spin density mainly resides at heavy pnictogen atoms, rather than delocalizes over Ge2E2 ring. They represent...
Mononuclear Pd(I) species are putative intermediates in Pd-catalyzed reactions, but our knowledge about them is limited due to difficulties accessing them. Herein, we report the isolation of a amido complex, [(BINAP)Pd(NHArTrip)] (BINAP = 2,2'-bis(diphenylphosphino)-1,1'-binaphthalene, ArTrip 2,6-bis(2',4',6'-triisopropylphenyl)phenyl), from reaction (BINAP)PdCl2 with LiNHArTrip. This has been characterized by X-ray crystallography, electron paramagnetic resonance, and multiedge Pd...

Abstract The reaction of Pd(OAc) 2 with free carbodicarbene (CDC) generates a Pd acetate trinuclear complex 1 via intramolecular C(sp 3 )−H bond activation at one the CDC methyl side arms. solid structure reveals capability to facilitate double dative two palladium centers in geminal fashion. This is attributed chelating mode CDC, which can frustrate π‐conjugation within framework. Such effect maybe also amplified by ligand‐ligand interaction. formation other gem ‐bimetallic Pd−Pd, Pd−Au,...

Unstrained cyclic ketones can participate in cooperative Suzuki-Miyaura cross-coupling type reaction using rhodium(I)-based catalyst via C-C bond activation. The regioselectivity indicates a trend where the most substituted side is activated and it controlled by beta-substituents. In this work, Density Functional Theory (DFT) calculations have been carried out to disclose underlying mechanism of ketone series arylboronate ylidene as ancillary ligand pyridine co-catalysts. computed energies...
A facile way of accessing the second lone pair carbodicarbene through “turn off” π-accepting ability flanking NHC is reported. The formation gem-double dative bimetallic from versatile mononuclear Pd and Ni complexes contributes to serve as a paradigm shift away relying on traditionally tedious synthetic methods access “hidden” pair. Most importantly, these results open new gateway for possible cooperative chemistry catalysis based C(0). More information can be found in Communication by...
