Chemoselective methylene hydroxylation in aromatic molecules
A chemoselective and reactive Mn(CF.sub.3-PDP) catalyst system that enables for the first time the strategic advantages of late-stage aliphatic CH hydroxylation to be leveraged in aromatic compounds. This discovery will benefit small molecule therapeutics by enabling the rapid diversification of aromatic drugs and natural products and identification of their metabolites.
APPLYING HANSEN SOLUBILITY PARAMETERS TO METAL-ORGANIC FRAMEWORK SYNTHESIS CONDITIONS
A method suitable for use in investigating synthesis conditions for metal-organic frameworks may include: identifying synthesis conditions that includes a first solvent system by which a metal-organic framework is successfully synthesized; and synthesizing the metal-organic framework under substantially the same synthesis conditions but with a second solvent system (or a comparable solvent system) having a difference (R.sub.a) between Hansen solubility parameters of 5 MPa.sup.0.5 or less as compared to the first solvent system.
Automated meta parameter search for invariant based anomaly detectors in log analytics
Systems and methods for automatically generating a set of meta-parameters used to train invariant-based anomaly detectors are provided. Data is transformed into a first set of time series data and a second set of time series data. A fitness threshold search is performed on the first set of time series data to automatically generate a fitness threshold, and a time resolution search is performed on the set of second time series data to automatically generate a time resolution. A set of meta-parameters including the fitness threshold and the time resolution are sent to one or more user devices across a network to govern the training of an invariant-based anomaly detector.
TRICARBONYL COMPLEXES OF TRANSITION METALS WITH BENZO-HETEROCYCLIC DERIVATIVES OF THE CYCLOPENTADIENYL ANION
Complex compounds of transition metals according to formula (1) wherein the M(CO).sub.3.sup.+ tricarbonyl-metal core forms a complex with the cyclopentadienyl anion linked to heterocyclic moieties of the benzothiazole, benzimidazole and benzoxazole families. The compounds exhibit high blood-brain barrier permeability and can be used in the diagnosis and/or treatment of diseases of the Central Nervous System.

AQUEOUS-BASED SYNTHESIS OF METAL ORGANIC FRAMEWORKS
Methods are provided for synthesizing metal organic framework compositions in an aqueous environment and/or in a mixed alcohol/water solvent. The methods can allow for formation of MOF-274 metal organic framework compositions, such as EMM-67 (a mixed metal MOF-274 metal organic framework composition). More generally, the methods can allow for formation of MOF structures that include disalicylate linkers in an aqueous environment and/or in a mixed alcohol/water solvent.
Process for Preparing a Transition Metal-Schiff Base Imine Ligand Complex
The present disclosure relates to a process for preparing a transition metal-Schiff base imine ligand complex. The process involves direct chelation of a Schiff base imine ligand by adding a transition metal halide in a halogenated fluid medium at a temperature in the range of 20 C. to 40 C. The process employs less hazardous reagents and mild reaction conditions to obtain the complex. The complex is efficient to be used as a catalyst for the production of disentangled ultra-high molecular weight polyethylene.
