Synthesis of phthalonitriles using a palladium catalyst

An easy synthetic method to obtain phthalonitriles from o-dibromobenzenes under mild conditions in high yields using Zn(CN)2 and a catalytic amount of tris(dibenzylideneacetone)dipalladium and 1,1′- bis(diphenylphosphino)ferrocene is described. Georg Thieme Verlag Stuttgart.

Porphyrin phthalocyanine covalent bifunctional graphene nonlinear nano hybrid material and preparation method thereof

The invention relates to a porphyrin phthalocyanine covalent bifunctional graphene nonlinear nanometer hybrid material and a preparation method thereof. The electron porphyrin and the electron-withdrawing phthalocyanine with the strong electron group are bonded to the surface of the graphene through radical addition reaction, charge is obtained through bridging of graphene, and third-order nonlinear performance of the organic - inorganic hybrid material is enhanced. In the invention, amino-substituted tetraphenylporphyrin and amino-substituted pull electron phthalocyanine are reacted through azo salt, so that a novel bifunctional organic-inorganic covalent functionalized nano hybrid material is successfully prepared. , The prepared material has more enhanced nonlinear optical performance in the nanosecond visible light field compared with the traditional materials, and has very strong reference significance.

Metal-Chelating 1,3-bis(2'-Pyridylimino)isoindolines

A variety of novel chelating 1,3-bis(2'-pyridylimino)isoindoline ligands were prepared and characterized including ligands substituted on both the pyridyl and isoindoline ring systems.Noteworthy are the first isoindoline ligands with solubility in aqueous media.A convenient preparation of 4-alkoxyphthalonitriles is reported; these compounds are readily obtained from 4-nitrophthalonitrile and are suitable starting materials for alkoxy-substituted ligands.
