Providing new methods for the selective functionalization of small molecules is highly desirable, because installing molecular diversity in a desired position, for example, allows one to modulate bioactive molecules. This work reports a method for the selective functionalization of anilines using hexafluoroisopropanol (HFIP) as a solvent to promote an acid-catalyzed hydroarylation of olefins. Mechanistic experiments revealed that HFIP both protonates the alkene and selectively enables anilines toward the electrophilic aromatic substitution. This powerful strategy has been applied to the functionalization of the anti-inflammatory mefenamic acid with chemocontrol and regiocontrol.

Alternatives to the use of pressurized hydrogen (H-2) in chemical syntheses are of growing interest and importance in developing safer protocols. Ammonia borane (AB), with its high hydrogen content and ability to release H-2 under mild conditions, is one potential solution. However, optimization of AB dehydrogenation and further the use of AB as a H-2 source to facilitate tandem one-pot reactions with both high activity and stability is an ongoing research challenge. In this work, monodisperse AuPd nanoparticle (NP) catalysts were synthesized and systematically studied for AB dehydrogenation, and Au-rich NPs were found to be the most active composition for AB methanolysis with a turnover frequency (TOF) of 160 min(-1) surpassing most Pd-based NP catalysts to date. More importantly, Au-rich NPs were also active in the one-pot tandem reduction of a series of nitro-groups and the hydrodehalogenation of mono- and polyhalogenated persistent chemical pollutants under mild reaction conditions using only a 2:1 molar ratio of AB to substrate. The AuPd catalyst was stable after ten reaction runs for AB methanolysis and five reaction runs for tandem one-pot reactions without a loss of activity or change in NP structure and morphology.

The development of more reactive, general, easily accessible, and readily avail-able Pd(II)-NHC precatalysts remains a key challenge in homogeneous catalysis. In this study, we establish air-stable NHC-Pd(II) chloro-dimers, [Pd(NHC)(mu-Cl) Cl](2), as the most reactive Pd(II)-NHC catalysts developed to date. Most crucially, compared with [Pd(NHC)(allyl)Cl] complexes, replacement of the allyl throw-away ligand with chloride allows for a more facile activation step, while effec-tively preventing the formation of off-cycle [Pd-2(mu-allyl)(mu-Cl)(NHC)(2)] products. The utility is demonstrated via broad compatibility with amide cross-coupling, Suzuki cross-coupling, and the direct, late-stage functionalization of pharmaceu-ticals. Computational studies provide key insight into the NHC-Pd(II) chloro-dimer activation pathway. A facile synthesis of NHC-Pd(II) chloro-dimers in one-pot from NHC salts is reported. Considering the tremendous utility of Pd-catalyzed cross-coupling reactions and the overwhelming success of [Pd(NHC)(allyl)Cl] precatalysts, we believe that NHC-Pd(II) chloro-dimers, [Pd(NHC)(mu-Cl)Cl](2), should be considered as go-to precatalysts of choice in cross-coupling processes.

Graphitic carbon nitride materials have attracted significant interest in recent years and found applications in diverse light-to-energy conversions such as artificial photosynthesis, CO2 reduction, or degradation of organic pollutants. However, their utilization in synthetic photocatalysis, especially in the direct functionalization of C(sp(3))-H bonds, remains underexplored. Herein, we report mesoporous graphitic carbon nitride (mpg-CN as a heterogeneous organic semiconductor photocatalyst for direct arylation of C(sp(3))-H bonds in combination with nickel catalysis. Our protocol has a broad synthetic scope (>70 examples including late-stage functionalization of drugs and agrochemicals), is operationally simple, and shows high chemo- and regioselectivities. Facile separation and recycling of the mpg-CN catalyst in combination with its low preparation cost, innate photochemical stability, and low toxicity are beneficial features overcoming typical shortcomings of homogeneous photocatalysis. Detailed mechanistic investigations and kinetic studies indicate that an unprecedented energy-transfer process (EnT) from the organic semiconductor to the nickel complex is operating.

A novel oxidative esterification of 1-arylprop-2-en-1-ols with toluene derivatives catalyzed by tetrabutylammonium iodide (TBAI) is reported. The optimization of the reaction conditions illustrates that each of experiment parameters including the catalyst, solvent, and oxidant is significant for present oxidative functionalization. This metal-free protocol has a broad substrate scope including the halogen groups for further functionalization and enriches the reactivity profile of allyl alcohol and toluene derivatives. In addition, this protocol represents a new transformation of allyl alcohol involving C-C bond cleavage and C-O bond forming.

N-Aryl-N’,N ‘-di(pyridin-2-yl)-and N-aryl-N’,N ”-bis(6-methylpyridin-2-yl) guanidines (1-4 and 5-7) were isolated in 75%-81% yields. Reactions of Pd(OAc)(2) with guanidines 2-7 carried out separately in toluene at 60 degrees C for 3 h afforded 8-13 respectively in 69%-80% yields. Compounds 1-13 were characterized by elemental analyses, HR-MS, IR and NMR (H-1 and C-13) spectroscopy. Molecular structures of guanidines 1, 4, 5 and 6 and those of 8-13 were determined by single crystal X-ray diffraction. The Pd(II) atom in 8-10 revealed trans geometry while that in 11-13 revealed cis geometry. DFT calculations were carried out on model compounds 9a (trans) and its hypothetical cis isomer, 9b and 12a (cis) and its hypothetical trans isomer 12b which indicated a very small energy difference between the 9a/9b pair (1.28 kcal/mol) whereas a large energy difference was observed between the 12a/12b pair (26.38 kcal/mol) in CH2Cl2. The catalytic utility of 9 in Heck-Mizoroki coupling reactions involving styrene and methyl acrylate and aryl bromides/aryl chlorides in the presence of NaOAc and excess of tetrabutylammonium bromide (TBAB) at 120 degrees C was explored. Both activated and de-activated aryl bromides and aryl chlorides were coupled with styrene and in addition, the aryl chlorides were coupled with methyl acrylate in the presence of 9 to afford the respective coupling products in 68% – > 99% yields. Neat reaction carried out with 9 and TBAB under the optimized condition released the colloidal Pd black as verified by EDAX, PXRD and SEM techniques thereby implying the heterogeneous nature of catalysis.
