Abstract Herein, an efficient route to enantioenriched organosilanes, containing two consecutive stereogenic centers, from enals and β‐silyl enones under carbene organocatalysis is described. Under mild reaction conditions, this transition‐metal‐free strategy exhibits a broad substrate scope, excellent diastereo‐ enantioselectivity.
Abstract Presented herein is the first direct alkylation and hydroxylation reaction between two different C(sp 3 )−H bonds, indolin‐2‐ones alkyl‐substituted N‐heteroarenes, through an oxidative cross‐coupling reaction. The catalyzed by a simple iron salt under mild ligand‐free base‐free conditions. environmentally benign, employs air (molecular oxygen) as terminal oxidant oxygen source for synthesis of O‐containing compounds, produces only water byproduct.
Coal resources, due to their cheapness and high-energy density, are widely used in large quantities, causing greenhouse gas emissions turn, thus need be utilized a resourceful way reduce carbon emissions. Herein, we designed an alternative route of value-added utilization using coal-based activated support loaded with Fe nanoparticles for CO2 hydrogenation liquid fuels. The derived tunable structure, elemental composition, defects, special surface area controlled by proposed two-step...
Accurate and rapid detection of potato surface defects is crucial for advancing intelligent sorting. To elevate accuracy as well shorten the computational load model, this paper proposes a lightweight Flaw-YOLOv5s algorithm defect detection. Firstly, Depthwise Separable Convolution (DWConv) used to displace original Conv in YOLOv5s network, aiming reduce burden parameters. Then, SPPF backbone network replaced by SPPELAN, which combines SPP with ELAN enable model perform multi-scale pooling...
We describe an unprecedented dual C–H functionalization of indolin-2-one via oxidative C(sp3)–H/N–H/X–H (X = N, C, S) cross-coupling protocol, which is catalyzed by a simple iron salt under mild and ligand-free conditions employs air (molecular oxygen) as the terminal oxidant. This method readily applicable for construction tetrasubstituted carbon centers from methylenes provides wide variety spiro N-heterocyclic oxindoles.
Direct and rapid construction of carbazoles has been successfully developed via carbene-catalyzed oxidative formal [4 + 2] annulation enals with 2-methyl-3-oxoacetate indoles. This metal-free reaction features a broad substrate scope, good functional-group tolerance, proceeds under mild conditions, can be easily scaled up.
The direct and rapid construction of carbazoles was achieved based on the reaction 2-methyl-indole-3-carbaldehydes enals promoted by Lewis acid LiCl DBU in a single operation.
An unprecedented method for the synthesis of highly functionalized indanes from arynes and α,γ-diketo esters is described. Importantly, mild nearly pH-neutral conditions ensure excellent functional group tolerance. Theoretical studies indicated that reaction proceeds through a benzocyclobutane intermediate.

Abstract Two star‐shaped molecules with benzene core and three naphthalene diimide ( NDI ) side arms were facilely prepared by two‐step imidization reaction from the 1,4,5,8‐naphthalenetetracarboxylic dianhydride. compounds showed similar UV –vis absorption band as well . It was found that they displayed bathochromic shift of their emission spectra in film compared solution, ascribing to aggregation between solid state. Reversible reduction process observed cyclic voltammetry low lying LUMO...
