Microwave assisted pyrolysis of halogenated plastics recovered from waste computers

Microwave Assisted Pyrolysis (MAP) of the plastic fraction of Waste from Electric and Electronic Equipment (WEEE) from end-life computers was run with different absorbers and set-ups in a multimode batch reactor. A large amount of various different liquid fractions (up to 76.6 wt%) were formed together with a remarkable reduction of the solid residue (up to 14.2 wt%). The liquid fractions were characterized using the following different techniques: FT-IR ATR, 1H NMR and a quantitative GC?MS analysis. The liquid fractions showed low density and viscosity, together with a high concentration of useful chemicals such as styrene (up to 117.7 mg/mL), xylenes (up to 25.6 mg/mL for p-xylene) whereas halogenated compounds were absent or present in a very low amounts.

Copper-Catalyzed Selective 1,2-Dialkylation of N-Heteroarenes via a Radical Addition/Reduction Process: Application for the Construction of Alkylated Dihydroazaarenes Derivatives

A highly efficient Cu-catalyzed 1,2-difunctionalization of various N-heteroarenes was developed with ether and alkyl halide at ambient temperature. This transformation involves the combination of oxidative coupling by Cu/TBHP and reduction process by 1,8-diazabicyclo[5.4.0]undec-7-ene. This method provides an efficient method to prepare various substituted dihydroazaarene derivatives via a free-radical process.

Dynamics of noncovalent supramolecular complexes. NMR study of the rotational barriers in chiral BINAP palladium(II) and platinum(II) bis(phosphane) complexes that resemble the minimal subunits of chiral polygons and polyhedra

In the reaction between 3-picoline, 2-bromo-5-methylpyridine, 2-methylquinoline, 3-methylisoquinoline, and [MCR-(+)-BINAP)][OTf]2 (M = Pd, Pt; BINAP = 2,2?-bis(diphenylphosphino)-1,1?-binaphthyl), the nature and the distribution of the products were investigated by various physical and spectroscopic methods. The alpha-substituents on the heteroaryl ring, such as the bromine atom in 2-bromo-5-methylpyridine or the methyl group in 2-methylquinoline, tend to promote the simultaneous formation of mono(heteroaryl)- and bis-(heteroaryl)-containing products. The reaction of the most sterically demanding 2-methylquinoline favors the formation of mono(heteroaryl) complexes exclusively within the limits of NMR detection. Reaction of 3-picoline with the chiral Pd(II) and Pt(II) bis(triflates) results in the formation of diastereomeric, square-planar, cationic complexes, due to the hindered rotation about the metal-nitrogen heteroaryl bond. 1H NMR variable-temperature studies of [M(R-(+)-BINAP)(3-picoline)2][OTf]2 were performed. The activation barriers for the rotation of the beta-picoline ligands around the M-N linkage axis were determined for [Pd-(R-(+)-BINAP)(3-picoline)2][OTf]2 and [Pt(R-(+)-BINAP)(3-picoline)2][OTf]2 by a kinetic line shape analysis of the methyl signals. The Gibbs free energy of activation was found to be 12(¡À0.5) kcal/mol for the Pd complex 15 and 14(¡À0.5) kcal/mol for the Pt complex 16. Ab initio calculations (HF/lanl2dz) of model complexes [dpe]Pd(HN=CH2)22+ and [dpe]Pt(HN= CH2)22+ (dpe = diphosphinoethylene) provided insights into the observed results. The nitrogen-metal pi-sigma-interaction is found to be stronger for the Pt complex, resulting in a higher energy barrier for the rotation around the Pt-N bond compared to the rotation around the Pd-N bond. A comparison is made between the covalent and coordinated Pt(II) complexes, and the similarities and differences of their dynamic behavior are discussed.

Predictive three-dimensional quantitative structure-activity relationship of cytochrome P450 1A2 inhibitors

The purpose of this study was to determine the cytochrome P450 1A2 (CYP1A2) inhibition potencies of structurally diverse compounds to create a comprehensive three-dimensional quantitative structure-activity relationship (3D-QSAR) model of CYP1A2 inhibitors and to use this model to predict the inhibition potencies of an external set of compounds. Fifty-two compounds including naphthalene, lactone and quinoline derivatives were assayed in a 96-well plate format for CYP1A2 inhibition activity using 7-ethoxyresorufin O-dealkylation as the probe reaction. The IC50 values of the tested compounds varied from 2.3 muM to over 40 000 muM. On the basis of this data set, a comparative molecular field analysis (CoMFA) and GRID/ GOLPE models were created that yielded novel structural information about the interaction between inhibitory molecules and the CYP1A2 active site. The created CoMFA model was able to accurately predict inhibitory potencies of several structurally unrelated compounds, including selective inhibitors of other cytochrome P450 forms.

N-Acylazinium Salts: A New Source of Iminium Ions for Ugi-Type Processes

A multicomponent reaction involving the interaction of azines (quinolines, isoquinolines, and phenanthridine) with activating agents (chloroformates, acid halides, and sulfonyl halides), isocyanides, and water is described. The products of this process, alpha-carbamoylated-1,2-dihydroazines, are the result of the addition of the isocyanide partner to the N-acylazinium salt formed in situ. This represents a new source of iminium ion equivalents for Ugi-type reactions.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! Read on for other articles about 1569-16-0!, 1125-80-0

Step 2: 2-BenzyI-3-methyl-l-(4-(trifluoromethyl)phenyl)-l,2,3,4-tetrahydro- isoquinoline; To a solution of 3-methylisoquinoline (1.0 g, 6.98 mmol) in THF (6 mL) was added benzyl bromide (0.78 mL, 6.63 mmol). After the addition was completed, the mixture was heated at 70 0C under N2 for 16 h. The mixture was cooled down to RT and THF (10 mL). Then, the mixture was cooled to 0 0C and (4- (trifluoromethyl)phenyl)magnesium bromide was added, and then stirred at RT for 16 h. After quenching with saturated ammonium chloride solution, the mixture was extracted several times with EtOAc. The combined organic extracts were dried over MgSO4 and concentrated. The residue was mixed with silica gel and the solid mixture was purified by silica gel flash column chromatography (30%- 100% EtO Ac/hexane, then 20% MeOH in DCM) to give a mixture of 2-benzyl-3 – methyl- 1 -(4-(trifluoromethyl)phenyl)-l ,2-dihydroisoquinoline & 2-benzyl-3- methyl-l-(4-(trifluoromethyl)phenyl)-isoquinolinium, which was used without further purification., 1125-80-0
