An efficient and BF3 center dot Et2O-catalyzed chemoselective synthesis of diversified 1,3-diarylisobenzofuran in a high yield has been described. The reaction proceeds through sequential hydroarylation-cyclization between 2-formylarylketones and electron-rich arenes/heteroarenes. Advantageous features of the developed methodology include operational simplicity, a broad substrate scope, and applicability towards gram scale synthesis. The utility of isobenzofuran derivatives as the diene was extended to the synthesis of [4+2] cyclo-adducts with DMAD and the synthesis of 1,2-dicarbonylarenes in good yields.

This report details a decarboxylative cross-coupling of (hetero)aryl carboxylates with iodoarenes in the presence of a gold catalyst (>25 examples, up to 96% yield). This reaction is site specific, which overcomes prior limitations associated with gold catalyzed oxidative coupling reactions. The reactivity of the (hetero)aryl carboxylate correlates qualitatively to the field effect parameter (F-ortho). Reactions with isolated gold complexes and DFT calculations support a mechanism proceeding through oxidative addition at a gold(I) cation with decarboxylation being viable at either a gold(I) or a silver(I) species.

The direct C-H arylation and acylation of azoles with carboxylic acids were achieved through Pd/Cu cooperative catalysis. Various biaryls and biaryl ketones were selectively produced in good to high yields from the same substrates. The key factor of high chemoselectivity was the choice of a suitable phosphine ligand: biaryls were generated selectively with dppp as the ligand, while biaryl ketones were obtained with high selectivity using dpph or Ph2PCy as the ligand.

Totally colorless, transparent, and highly refractive poly(phenylene thioether ether)s (PPTEs) containing thianthrene-2,7-disulfanyl moiety were developed in this study. A new 4,4′-diol aromatic compound, 2,7-(4,4′-diphenol)thiothianthrene (DPTT), with a high sulfur content was designed and synthesized to develop polymers with high refractive indices and high thermal stabilities. The PPTEs were prepared by polycondensation of DPTT with organic dihalogen compounds, such as 2,6-difluorobenzonitrile (DFBN) and 4,6-dichloro-2-(methylthio) pyrimidine (DCMP). The obtained polymers showed good thermal stabilities such as relatively high glass transition temperatures (T(g)s) in the range of 153-176 degrees C and 5% weight loss temperatures (T-5%) over 344 degrees C. The cut-off wavelengths (lambda(0)) of the PPTE films are shorter than 343 nm, and they have a transmittance higher than 93% at 550 nm. The combination of the pyrimidine and high sulfur-containing thianthrene derivatives provides the PPTEs with a high refractive index of 1.7204 and a small birefringence of 0.0106 at 637 nm.

The development of carbonaceous materials as metal-free catalysts integrating different types of catalysis in a single system represents a significant advance in cascade/tandem organic synthesis. Zero-dimensional carbon dots with tuneable optical properties and easily modifiable surface functionalities can be harnessed as a carbocatalyst for merging photooxidation and acid-catalyzed reactions in one pot. Herein, we explore carbon dots decorated with hydrogen sulfate groups as a photocatalyst for the dehydrogenative cross-coupling of xanthenes with ketones, arenes and 1,3-dicarbonyl compounds that showed high efficiency and selectivity under visible-light irradiation. The sulphated carbon dots demonstrate dual catalytic properties, wherein they induced the rapid photooxidation of xanthenes in the presence of molecular oxygen to form a hydroperoxy intermediate followed by coupling of nucleophiles catalysed by the acidic surface functional groups. The methodology represents an operationally simple pathway for the generation of C-C coupling products in a short reaction time with wide substrate scopes under mild conditions. The catalyst is easily separable and can be reused over multiple cycles with good efficiency.

A novel path has been developed for the conversion of carboxylic acids into the corresponding N -acylbenzotriazoles by using 2,2-dipyridyl disulfide/PPh (3) in anhydrous dichloromethane in the presence of 1 H -benzotriazole. Mild reaction conditions, short reaction time, easy in handling, wide substrate scope, availability of reagents involved, and moreover avoiding the use of base makes this protocol quite useful for the laboratory practices for N -acylbenzotriazole synthesis.

Density functional theory and its time-dependent extension are employed to investigate the intermolecular hydrogen-bonding- (Inter-HB-) induced fluorescence enhancement of benzaldehydes. The fluorescence quenching mechanism of benzaldehydes in chloroform is attributed to the low energy gap between the lowest pi pi* and n pi* states at Franck-Condon (FC) point and conical interaction between pi pi** and n pi* states. The Inter-HB between the aldehyde group of benzaldehydes and methanol can considerably increase the energy gap between pi pi* and n pi* states at the FC point, and this type of hydrogen bond is strengthened in the excited pi pi* state, thereby precluding the nonradiative transition from n pi* state and enhancing fluorescence. The Inter-HB between the hydroxy group of benzaldehydes and methanol is considerably stronger than that between the aldehyde group of benzaldehydes and methanol; which has a little effect on the energy gap of pi pi* and n pi* states. Therefore, if Inter-HB exists between the hydroxy group of benzaldehydes and methanol, then it will play an important role in ground and excited pi pi* states, and fluorescence enhancement by Inter-HB between the aldehyde group of benzaldehydes and methanol will be absent. Our proposed mechanism can explain the experimental observations and differs from that of proximity effects.

Abundant aromatic carboxylic acids exist in great structural diversity from nature and synthesis. To date, the synthetically valuable decarboxylative functionalization of benzoic acids is realized mainly by transition-metal-catalyzed decarboxylative cross couplings. However, the high activation barrier for thermal decarboxylative carbometalation that often requires 140 degrees C reaction temperature limits both the substrate scope as well as the scope of suitable reactions that can sustain such conditions. Numerous reactions, for example, decarboxylative fluorination that is well developed for aliphatic carboxylic acids, are out of reach for the aromatic counterparts with current reaction chemistry. Here, we report a conceptually different approach through a low-barrier photoinduced ligand to metal charge transfer (LMCT)-enabled radical decarboxylative carbometalation strategy, which generates a putative high-valent arylcopper(III) complex, from which versatile facile reductive eliminations can occur. We demonstrate the suitability of our new approach to address previously unrealized general decarboxylative fluorination of benzoic acids.
