An Amine Functionalized Metal-Organic Framework as an Effective Catalyst for Conversion of CO2 and Biginelli Reactions

A highly porous and thermally stable anionic Zn(II)-framework, {[(CH3)2NH2+]2[Zn3((μ3-O))(L)2(H2O)]·4DMF·2H2O}n (1), having exposed metal sites and pendant amine groups has been synthesized adopting the solvothermal technique. This anionic 3D framework showed two-fold interpenetration with 45.1% void volume. It has a 3,6-c binodal net with rare sit 3,6-conn topology. The metal bound aqua ligand could be easily removed along with the guest molecules in the lattice upon activation to afford the desolvated framework 1′. This produced exposed metal sites that, along with the pendant amine groups incorporated in the ligand, generated a coordination space in the framework to make it an outstanding heterogeneous catalyst for the chemical fixation of CO2 with various epoxides under atmospheric pressure and in the three-component Biginelli reaction with different aldehydes, ethyl acetoacetate, and urea to afford dihydropyrimidinones.

Stable Thioaminyl Radicals Having Functional Groups: Generation, ESR Spectra, Isolation, X-ray Crystallographic Analyses, and Magnetic Characterization of N-(Arylthio)-4-(ethoxycarbonyl)-2,6-diarylphenylaminyls, N-(Arylthio)-4-acetyl-2,6-diarylphenylaminyls, and N-(Arylthio)-4-cyano-2,6-diarylphenylaminyls

Oxidation of N-(arylthio)-4-(ethoxycarbonyl)-2,6-diarylanilines (9), N-(arylthio)-4-acetyl-2,6-diarylanilines (10), and N-(arylthio)-4-cyano-2,6-diarylanilines (11) with PbO2 yielded quite persistent N-(arylthio)-4-(ethoxycarbonyl)-2,6-diarylphenylaminyls(4), N-(arylthio)-4-acetyl-2,6-diarylphenylaminyls (5), and N-(arylthio)-4-cyano-2,6-diarylphenylaminyls (6), respectively, and they were isolated as pure radical crystals. On the other hand, N-(arylthio)-4-nitro-2,6-diarylphenylaminyls (6), and N-(arylthio)-4-chloro-2,6-diarylphenylaminyls (7), were unstable and soon decomposed. The X-ray crystallographic analyses of N-[(2,4-dichlorophenyl)thio]-4-acetyl-2,6-diphenylphenylaminyl (5c) and N-[(2,4-dichlorophenyl)thio]-4-cyano-2,6-diphenylphenylaminyl (6c) showed that the Ph-N-S-Ph π-framework is planar, and the 2- and 6-phenyl groups are twisted from the coplane. The ESR studies for 4-8 showed that their hyperfine coupling constants are nearly identical to each other and that the unpaired electron is extensively delocalized onto the anilino benzene ring and the arylthiyl group. The magnetic susceptibility measurements were carried out for five thioaminyl radical crystals and showed that one radical couples ferromagnetically with 2J/kB = 16.0 K, and the other four radicals couple antiferromagnetically with 2J/kB = -15.6 to -194.6 K or θ = -0.6 to -5.0 K.
