Highly modular chiral amino diol derivatives, e.g. I, have been used as organocatalysts in the enantioselective α-chlorination of cyclic β-keto esters. Optimization of the catalyst structure and the reaction conditions has allowed the synthesis of optically active α-chlorinated products with high enantioselectivities (up to 96% ee) using inexpensive com. available N-chlorosuccinimide (NCS) as the chlorine source under mild conditions.Dimethoxydiphenylmethane (cas: 2235-01-0) were involved in the experimental procedure.

The research results were published in《ACS Applied Polymer Materials》 in 2020.Computed Properties of C12H12N2O The article conveys some information:

Soluble, thermally, and dimensionally stable polyarylamides have been a long-standing challenge for polymer chemists and materials scientists. Herein, we designed and synthesized a series of polyarylamides with various contents of the seven-membered carbocycle unit of 1,2:4,5-dibenzocycloheptadiene (DBCHD) as the linkage in the polymer backbones. In comparison to their analog with an ether linkage, these advanced polyarylamides showed improved thermal stability (5% weight loss temperature, 413-480°) and elevated glass transition temperatures (218-243°) depending on the content of the DBCHD unit. Given the good solubility in polar aprotic solvents, the polyarylamide films were prepared by simple and straightforward solution casting, which presented excellent optical transparency and low coefficient of thermal expansion (CTE). The polyarylamide with the highest content of DBCHD (43.5 wt %) showed a CTE value of 41.0 ppm/K in the temperature range of 0-150°, which is 43% lower than that of the corresponding ether-linked polyarylamide film. Variable-temperature 1H NMR demonstrated that the nonplanar and moderately rigid structural features of DBCHD units in polymer backbones are the key influence factors that contribute to thermal stability and reduced thermal expansion. To complete the study, the researchers used 3-(4-Aminophenoxy)aniline (cas: 2657-87-6) .

A novel, mild, and chemoselective method was developed for the preparation of gem-diacetates from aldehydes and Ac2O in the presence of TiF4 (1-5 mol%) under solvent-free conditions at room temperature The reaction showed a high chemoselectivity toward aldehydes in the presence of ketones. Moreover, TiF4 also catalyzed the deprotection of gem-diacetates to the corresponding aldehydes in water. .This efficient and simple method has several benefits, including the use of an inexpensive catalyst, solvent-free conditions, mild reaction temperatures, and high yields, which make it both cost-effective and environmentally friendly. And Dimethoxydiphenylmethane (cas: 2235-01-0) was used in the research process.

The article was appeared in 《International Journal of Adhesion and Adhesives》. They have made some progress in their research.COA of Formula: C12H12N2O The article mentions the following:

Microwave energy was investigated to cure phenylethynyl-end-capped polyimide adhesive using an industrial microwave oven at a frequency of 2.45 GHz and the adhesive properties, thermal performance and curing mechanism for bonding stainless steel were evaluated. The results are compared with those of thermal cured samples. It was demonstrated that while the lap shear strength properties and thermal performance of microwave cured samples were almost as good as those cured via a thermal process, the microwave curing process resulted in a significant reduction in the process cycle time and power consumption. The Fourier transform IR (FTIR) spectroscopy and XPS anal. of the cured resin structures suggested that there was no obvious difference in the chem. reactions taking place during the microwave and the thermal cure processes.3-(4-Aminophenoxy)aniline (cas: 2657-87-6) were involved in the experimental procedure.

Reported equilibrium mole fraction solubilities of sinapic acid (3) in {DMSO (1) + water (2)} and {Carbitol (1) + water (2)} mixtures at several temperatures were analyzed in terms of the Hildebrand solubility parameter of these aqueous mixtures Moreover, the preferential solvation parameters of sinapic acid in these aqueous saturated mixtures at (298.15 and 313.15) K were determined based on the inverse Kirkwood-Buff integrals (IKBI) as widely described in the literature. Sinapic acid is preferentially solvated by water in water-rich mixtures, i.e. (0.00 <x1 < 0.21 in {DMSO (1) + water (2)}) and (0.00 <x1 < 0.12 in {Carbitol (1) + water (2)}) but preferentially solvated by the cosolvents in the other mixtures composition In the former cases these results could be interpreted as a consequence of hydrophobic hydration around the non-polar moieties of sinapic acid. Moreover, in the last cases, the observed trends could be due to the Lewis acidic behavior of sinapic acid in front of DMSO or Carbitol mols. because both cosolvents exhibit higher Lewis basic character than water, as indicated by the resp. solvatochromic parameters. A single cosolvency model for representing the equilibrium solubility of sinapic acid in binary solvents at various temperatures was also provided based on a combination of Hansen solubility parameters and Jouyban-Acree model.

PDP-6 is preferentially solvated by water in water-rich mixtures of {Transcutol (1) + water (2)} system but preferentially solvated by Transcutol in mixtures of 0.13 < x1 < 1.00.

Otherwise, PDP-6 is preferentially solvated by PEG 400 in all the aqueous mixtures Moreover, in the systems where preferentially solvation of PDP-6 by cosolvents are observed, these results could be due to the Lewis acidic behavior of PDP-6 in front of Transcutol or PEG 400 mols. because these cosolvents exhibit higher Lewis basic behavior than water.
