In this work, we synthesized thulium (Tm3+) modified TiO2 nanoparticles by a facile sol-gel route. We show that Tm3+-modified TiO2 exhibit superior photocatalytic activity than pure TiO2 towards gas-phase degradation of acetaldehyde, o-xylene, and their mixture. The photocatalytic activity enhances with the increasing Tm content from 0.1 to 0.5 mol%. The 0.5 mol%Tm-TiO2 sample demonstrated the highest photodegradation efficiency (> 90.0%) for acetaldehyde and o-xylene. According to the systematic characterization such as photoluminescence (PL), photocurrent, up-conversion spectra, UV-Vis diffuse reflectance spectroscopy and electron spin resonance (ESR) analysis, the enhanced photocatalytic performance can be attributed to introducing the new Tm-4f states between the original band gap of TiO2, which led to the increase of efficiency of light-induced electron-hole separation and the increase of hydrophilicity which resulted in the increased adsorption capacity towards acetaldehyde and o-xylene. Gas Chromatography-Mass Spectrometer (GC-MS) analysis suggested that o-xylene was first oxidized to o-benzaldehyde, which was eventually converted to butanol before being mineralized into CO2. However, new intermediates including phthalide, o-methyl acetophenone, naphthalene and 5-Methyl-4-octanone were detected in the mixture.

An inexpensive, powerful, and eco-friendly method for transition-metal-free oxidative C(sp(3))-H bond lactonization was developed using sodium peroxydisulfate as the sole oxidant. The cyclization of 2-alkylbenzoic acids containing a primary, secondary or tertiary carbon at the benzylic position proceeded smoothly, affording a variety of lactone derivatives. Furthermore, various functional groups such as halogen, cyano, nitro and hydroxy groups were tolerated under the reaction conditions.

A series of 1,3-indandione-terminated pi-conjugated quinoids were synthesized by alkoxide-mediated rearrangement reaction of the respective alkene precursors, followed by air oxidation. This new protocol allows access to quinoidal compounds with variable termini and cores. The resulting quinoids all show LUMO levels below -4.0 eV and molar extinction coefficients above 10(5) L mol(-1) cm(-1). The optoelectronic properties of these compounds can be regulated by tuning the central cores as well as the aryl termini ascribed to the delocalized frontier molecular orbitals over the entire molecular skeleton involving aryl termini. n-Channel organic thin-film transistors with electron mobility of up to 0.38 cm(2) V-1 s(-1) were fabricated, showing the potential of this new class of quinoids as organic semiconductors.

Reductions of amides and esters are of critical importance in synthetic chemistry, and there are numerous protocols for executing these transformations employing traditional batch conditions. Notably, strategies based on flow chemistry, especially for amide reductions, are much less explored. Herein, a simple process was developed in which neat borane dimethylsulfide complex (BH3 center dot DMS) was used to reduce various esters and amides under continuous-flow conditions. Taking advantage of the solvent-free nature of the commercially available borane reagent, high substrate concentrations were realized, allowing outstanding productivity and a significant reduction in E-factors. In addition, with carefully optimized short residence times, the corresponding alcohols and amines were obtained in high selectivity and high yields. The synthetic utility of the inexpensive and easily implemented flow protocol was further corroborated by multigram-scale syntheses of pharmaceutically relevant products. Owing to its beneficial features, including low solvent and reducing agent consumption, high selectivity, simplicity, and inherent scalability, the present process demonstrates fewer environmental concerns than most typical batch reductions using metal hydrides as reducing agents.

Phthalides as the crucial core skeletons are found extensively in natural products and biological active molecules. Herein we disclose an asymmetric allylation of 3-hydroxyisoben-zofuran-1(3H)-ones with boron allylation reagents to construct chiral phthalide derivatives. The simple Bi(OAc)(3)/chiral phosphoric acid catalytic system proves to be efficient in this method, delivering the desired chiral 3-allylisobenzofuran-1(3H)-ones in good yields (up to 99%) and high enantioselectivities (up to 99.5:0.5 e.r.) under mild conditions. The large-scale reaction and diverse transformations of products to various scaffolds with potential biological activities render it more attractive. Moreover, the mechanism was preliminarily explored by control reactions, mass spectrometry, deuterium experiment, and DFT calculations.

A new, simple, and rapid photochemical reaction of o-phthalaldehyde with C-60 has been disclosed. This reaction afforded exclusively the unanticipated C-60-phthalide derivative 11 in good yield. The formation of this product is consistent with the intervention of a key free-radical intermediate -a benzylic radical- in the course of the reaction. The structure of 11 has been determined by the combined use of experimental and theoretical NMR studies. In the course of this study we further disclosed a new mode of radical reactivity of C-60 with a series of substituted phthalides (2, 15-17) catalyzed by tetrabutylammonium decatungstate.

Chiral alpha-substituted 1,3-dihydroisobenzofurans are key scaffolds in a number of bioactive natural products and synthetic pharmaceuticals. However, catalytic asymmetric approaches have been rarely developed. Here, a redox deracemization technology is adopted to address the catalytic asymmetric synthesis. A broad range of alpha-aryl substituted 1,3-dihydroisobenzofurans are effectively deracemized in high efficiency with excellent ee. alpha-Alkynyl substituted ethers were also compatible with the deracemization technology.
