An apparatus for producing metal organic frameworks, comprising: a tubular flow reactor comprising a tubular body into which, in use, precursor compounds which form the metal organic framework are fed and flow, said tubular body including at least one annular loop.

This invention discloses the first example of palladium(II)-catalyzed -C(sp.sup.3)-H iodination or arylation of a wide range of ketones by using a commercially available aminooxyacetic acid auxiliary. This L, X-type directing group overcomes the limitation of the transient directing group approach for -C(sp.sup.3)-H functionalization of ketones. Practical advantages of this method include simple installation of the auxiliary without chromatography, exceptional tolerance of a-functional groups, double bonds and triple bonds and rapid access to diverse sterically hindered quaternary centers.

Metal-organic frameworks (MOFs) may have Zn(II), Pb(II), and/or Cd(II) as a central metal ion; a 4,4-bipyridylethylene (bpe) ligand as a first ligand; and fumaric acid (fum) and/or oxalic acid (ox) as a second ligand, wherein the 4,4-bipyridylethylene ligands are stacked in the MOF, and wherein a distance between two consecutive 4,4-bipyridylethylene ligands is less than 5 . Cycloadditions, particularly photoinduced [2+2] cycloadditions may be catalyzed by such MOFs, and/or the conversion of photoinduced [2+2] cycloadditions in inventive MOFs may be increased by mechanical force, such as by grinding.

A method of making a metal organic framework (MOF)-polymer composite material includes forming a homogeneous solution comprising a solvent, a metal salt, a polymer which is soluble in the solvent, and a reactant which can be synthesized to provide an organic linker during formation of a MOF structure, synthesizing the homogeneous solution to crystallize a MOF structure in the homogenous solution to yield the MOF structure distributed in a remainder solution, applying an antisolvent to the remainder solution with the MOF structure distributed in the remainder solution to form a polymer-rich phase, where the MOF structure is integrated into the polymer matrix during forming of the polymer matrix to produce a MOF-polymer composite material. The MOF-polymer composite material can be formed on a substrate to produce a MOF structured object, which can be a membrane, film, or other object.

Embodiments of the present disclosure describe a catalyst and/or a precatalyst, in particular a single site catalyst and/or a single site precatalyst, for the oxidation and/or ammoxidation of olefins to produce aldehydes and/or nitriles, methods of preparing a corresponding catalyst and/or precatalyst, in particular single site catalyst and/or single site precatalyst, and methods of using said catalyst and/or precatalyst, in particular said single site catalyst and/or single site precatalyst, to produce aldehydes and/or nitriles.
