A mild tandem oxidative functionalization of allyl aromatic hydrocarbons was accomplished using the catalytic system of Pd(OAc)2/DMA under 1 atm O2. The green twofold C-O bond formation involving double allylic C-H oxygenation unlocks opportunities for markedly different synthetic strategies. Moreover, the reaction affords aryl alpha,beta-unsaturated esters directly from readily available terminal olefins in moderate to good yields with excellent chemo- and stereoselectivities.

Three kinds of aromatic poly(amic acid)s that contain acetylene groups in the main chain were cured in air at temperatures up to 400C to give intermolecular crosslinked polyimides. The crosslink reactions occurred at the internal acetylene units and the chemical structures thus generated have been investigated by thermal analyses (thermogravimetric analyses (TGA) and differential scanning calorimetry (DSC)) and high resolution solid-state 13C cross polarization (CP)/magic angle spinning (MAS) NMR. The thermal analyses indicated that broad exotherms are observed above 300C for all the polyimides cured at 200, 300, and 350C, and the exothermal reactions do not eliminate volatile components from the polyimide structure. The 13C CP/MAS NMR spectra of pyromellitic dianhydride/3,3?-diaminodiphenyl-acetylene (PMDA/m-intA) polyimides show that the signal intensities of the acetylene carbons and the phenyl carbons directly bonded to the acetylene units significantly decrease after curing above 300C, which indicates that crosslink reactions occurred during curing. In addition, a signal that can be assigned to the C1-carbon of biphenyl structure newly appears after curing, and it grows as the curing temperature increases from 350 to 400C. From the examination of the chemical shift of the new signal, the most probable crosslink mechanism is the Diels-Alder cycloaddition that occurs between two phenylethynyl groups and provides polycyclic aromatic structures containing biphenyl linkages. The DSC, TGA, and NMR spectra suggest that the same crosslink reactions occur in the other two polyimides, although they occur in the different temperatures ranges. The signal intensities in the NMR spectra indicate that 40-55% of the acetylene carbons remained unreacted even after curing at 400C. This situation significantly differs from the cases of acetylene- and phenylethynyl-terminated polyimides, in which almost no acetylene units remained after curing as a result of a variety of crosslink reactions. The crosslink reactions occurring at the internal acetylene units are more selective and uniform due to the preferred layer packing of the diphenylacetylene groups and the restricted molecular motion in the solid state.

A contemporary method is reported for the Pd(OAc)2/AgOAc catalytic system based bidentate ligand directed, regioselective C-H activation and C-C bond formation at the C-3 position of thiophene- and furan-2-carboxamides, which are derived from 8-aminoquinoline or 2-(methylthio)aniline. The Pd-catalyzed C-H arylation of thiophene- and furan-2-carboxamides with a variety of aryl iodides and heteroaryl iodides was highly regioselective and afforded C-3-arylated thiophene-2-carboxamides and furan-2-carboxamides in good to very good yields. The bidentate ligand directed Pd(OAc)2/AgOAc based strategy was also successfully employed for benzylation and alkylation reactions of the thiophene-2-carboxamides. These reactions occurred with high regioselectivity to afford the C-3-benzylated and C-3-alkylated thiophene-2-carboxamides in good yields. The observed regioselectivity of these reactions was confirmed by X-ray crystal structure analyses of compounds 3e, 5a, and 6a.

Novel N-substituted phthalimides (2-substituted 1H-isoindole-1,3- diones) were prepared, and their effects on tumor necrosis factor-alpha (TNF- alpha) production by human leukemia cell line HL-60 stimulated with 12-O- tetradecanoylphorbol 13-acetate (TPA) or okadaic acid (OA) were examined. A structure-activity relationship study of the N-phenylphthalimides and N- benzylphthalimides revealed that their enhancing effect on TPA-induced TNF- alpha production by HL-60 cells and their inhibiting effect on OA-induced TNF- alpha production by HL-60 cells are only partially correlated.

Cellular immobilisation (CI) is a method characterised by restricting the cells to a delimited area while preserving their metabolic, catabolic, and catalytic activities Biodegradation of contaminants is one of the potential applications of CI. Immobilised cells can achieve to degrade the degradation of toxic substances with higher efficiency than cells in a free state. free cells. The aim of this work was to compile the most important aspects of CI as a strategy for the degradation of pesticides. We discuss the main targeted chemical substances, the used microorganisms, materials, and techniques, as well as their advantages, and limitations We highlight increases in the percentage of degradation, greater stability, protection, and tolerance to pesticides when a CI strategy is implemented.
