Diphosphametacyclophanes: Structural and electronic influences of substituent variation within a family of bis(diketophosphanyl) macrocycles

The condensation of MeP(SiMe3)2 with a series of 5-substituted isophthaloyl chlorides (5-R′C6H3-2,6-{C(O)Cl}2) affords the diphosphametacyclophanes m-{-C(O)-C6H3-5-R′-(C(O)PMe)}2 (R′ = I, Me, tBu, Ph, and p-NCC6H4); the analogues m-{-C(O)-C5H3N-(C(O)PMe)}2 and m-{-C(O)-C6H4-(C(O)PPh)}2 are similarly obtained in preference to higher oligomers, in contrast to precedent reports. The cyclophanes all adopt butterfly-like conformations in the solid state with the P-organyl substituents adopting mutually exo arrangements. Structural and computational data suggest the nature of the 5-R substituent is key in directing the inter-ring angle and the extent of LUMO stabilization about the diketophophanyl scaffold. The latter is substantiated by UV/vis spectroscopy and cyclic voltammetry, which demonstrate these cyclophanes to be appreciably comparable to the diketophosphanyl systems commonly explored in the context of organic electronic materials; intriguingly, the distinct dikeophosphanyl moieties within the macrocycles appear effectively “insulated” by the macrocycle geometry, rather than acting as a through-conjugate.

A Highly Stable Nanotubular MOF Rotator for Selective Adsorption of Benzene and Separation of Xylene Isomers

A remarkably stable tubular 3D Zn-MOF with hexagonal channels and a rare ptr topology was prepared under solvothermal conditions for liquid and vapor phase adsorption and separation of the C6-8 aromatic compounds. The material showed preferential affinity for benzene and can effectively separate benzene from its organic analogues under ambient conditions in both vapor and liquid phases. Furthermore, it exhibited preferable uptake of p-xylene over other C8 xylenes.

Process For Production of 5-Phenylisophthalic Acid

The present invention provides an industrially advantageous process for producing 5-phenylisophthalic acid, which process attains excellent selectivity and yield and also realizes recovery and reuse of a catalyst. The process for producing 5-phenylisophthalic acid represented by formula (1) is characterized in that the process includes the following steps (A) to (C): (A) reacting m-xylene with cyclohexene in the presence of hydrogen fluoride and boron trifluoride, to thereby produce 1-cyclohexyl-3,5-dimethylbenzene;(B) dehydrogenating the 1-cyclohexyl-3,5-dimethylbenzene produced in step (A) in the presence of a dehydrogenation catalyst, to thereby produce 3,5-dimethylbiphenyl; and(C) dissolving the 3,5-dimethylbiphenyl produced in step (B) in a solvent and oxidizing the 3,5-dimethylbiphenyl in the co-presence of an oxidation catalyst, to thereby produce 5-phenylisophthalic acid.
