Recent advances in nitrene chemistry from acyclic precursors are reviewed this paper.
Reaction of the N-benzylidene-1-naphthylamine with CoMe(PMe3)4 afforded hydrido CNC pincer cobalt complex CoH(PMe3)2[(C6H4)CH═N(C10H6)] (1) via double C–H bond activation. In 1H NMR spectrum, a triplet at −18.98 ppm is typical signal ligand (Co–H). Complex 1 reacted haloalkane (CH3I and EtBr) to deliver CoX(PMe3)2((C6H4)CH═N(C10H6)) (X = I (2); Br (3)). However, reactions HCl trifluoroacetic acid (TFA) delivered HCoCl(PMe3)2((C6H4)CH═N(C10H7)) (4) HCo(OCOCF3)(PMe3)2((C6H4)CH═N(C10H7)) (5)...

Pine wilt disease has caused significant damage to China's ecological and financial resources. To prevent its further spread across the country, proactive control measures are necessary. Given low accuracy of traditional models, we have employed an enhanced LightGBM model predict development trend pine in China. By incorporating anthropogenic factors such as volume wood imports from 2017 2022, density graded roads, number adjacent counties, presence processing factories, well natural like...
Abstract It has been established that assembling chiral nanostructures using a circularly polarized laser is formidable due to their symmetry mismatch. Traditionally, complex light fields or precursors are considered prerequisites for optical self‐assembly. Herein, an unexpected seed symmetry‐breaking (SSB) effect reported, through which not only structures readily assembled by in controllable manner, but the physical mechanism of assembly reported so far also clarified. The SSB refers...
ABSTRACT Tertiary alcohols are generally considered difficult to oxidize. However, in this work, it was found that catalyzed by (NH 4 ) 2 Ce(NO 3 6 (CAN) and the presence of catalytic trifluoroacetic acid (TFA), selective oxidative C‐C bond cleavage tertiary could be achieved using O flow produce carbonyl compounds. The benefits method include use simple inexpensive catalysts, as well environmentally friendly nature process. This research significantly broadens scope alcohol oxidation...
Indole scaffolds, pivotal structural motifs in organic chemistry, have garnered sustained interest due to their prevalence pharmaceuticals, agrochemicals, and natural products. This study establishes a novel umpolung activation strategy...
Mechanochemical S(VI) exchange reactions are developed on chiral S(VI)–F and S(VI)–Cl centers that fast, solvent–free, high–yielding, enantiospecific. This approach is used to synthesize a range of sulfonimidate esters sulfonimidamides from sulfonimidoyl fluorides chlorides under mild reaction conditions. The broad scope this method demonstrated by its successful reactivity with phenols both primary secondary anilines. Furthermore, substitution in 4–nitrophenol‐derived species substituted...
In this work, switchable synthesis of isoquinolin-1-one and 3-hydroxylisoquinolin-1,4-dione from 2-alkynylbenzamide is reported. The transformation works well with good yields a broad reaction scope. synthetic switch for providing enabled by the use N2 or O2 atmosphere. Mechanism studies show that proceeds in regioselective manner via N-center radical 6-endo-dig aza-cyclization pathway.
A TBAB-controlled switchable synthesis of isocoumarin-1-imine and isobenzofuran-1-imine from 2-alkynylbenzamide in water is described this paper.
A highly efficient [8 + 2] cycloaddition reaction of azaheptafulvenes with α-chloro aliphatic aldehydes enabled by N-heterocyclic carbene catalysis is presented, delivering cis-cycloheptatriene-fused γ-lactams good yields, moderate to diastereoselectivies, and excellent enantioselectivies. This higher order can be readily expanded the gram scale, products could further transformed other useful compounds via simple operations.
Totally different functionalization and construction as two fundamental synthetic protocols have long been applied to furnish azaarene variants. Here, a novel radical-based functionalization-oriented strategy by exploiting the electronic properties of azaarenes high reactivity radicals is developed. Under photoredox catalysis platform, robust ability such an artful combination with disclosed in synthesis valuable 3-azaarene-substituted densely functionalized pyrroles. In addition use readily...
Polyaniline-supported metal nanoparticles (M@PANIs) have been widely employed as catalysts for organic reactions. Traditionally, the catalytic activities of materials can be improved by introducing functional groups onto aniline monomers, but it may enhance catalyst cost and reduce production yield material. This work reports a new strategy improving activity M@PANIs. It was found that induced visible light in presence polymeric carbon nitride copper dopant, oxidative polymerization simple...
A facile and efficient electrocyclization for the synthesis of polyfunctionalized benzene naphthalene derivatives was reported. As a result ready availability starting materials simple operation, this type reaction has potential utility in organic synthesis.
Construction of a new benzene via the electrocyclization diene–allene is an efficient protocol to access polysubstituted benzenes from simple, readily available starting materials. In this paper, we present comprehensive study heteroatom-promoted propargyl–allenyl isomerization and for facile synthesis polyfunctionalized naphthalenes. As result accessible materials, simple operation, mild conditions, reaction should be appealing strategy in organic synthesis.
