Method for reduction of organic molecules
A method for the reduction organic molecules comprising a Ruthenium-Triphosphine complex with aromatic ligands at the phosphors which are ortho or meta substituted.
SALT OF QUINAZOLINE DERIVATIVE, PREPARATION METHOD THEREFOR AND APPLICATION THEREOF
A salt of a quinazoline derivative (N-[4-(3-chlorine-4-fluoanilino)]-7-(3-morpholinepropanol)-6-(2-fluoroacrylamide)-quinazoline, the structure thereof is as represented by formula I). Compared with a known quinazoline derivative, the salt of the quinazoline derivative has one or more improved properties and at least has better water solubility, wherein a citrate, a benzene sulfonate, and an ethanedisulphonate thereof further have better crystallinity and are not easy to absorb moisture.

PREPARATION OF TMTHF
A process for the preparation of 2,2,5,5-tetramethyltetrahydrofuran (TMTHF) includes contacting a TMTHF precursor with a solid catalyst, where the TMTHF precursor is 2,5-dimethylhexane-2,5-dioland/or 2,5-dimethyl-4-hexen-2-ol, and where the solid catalyst is a beta zeolite. TMTHF produced by the process may be used as a solvent.

Apparatus and continuous flow process for production of boronic acid derivatives
A process for a continuous production of a boronic acid derivative based on a Matteson boronic ester homologation and an apparatus of performing the process are disclosed.
Oligomeric (TH)FP, production and uses therefor
A method for the isolation of oligomeric 2, 2-difurylpropane (DTHFP) suitable for use on an industrial scale. A method can include using oligomeric 2, 2-difurylpropane, in particular, its use can be as a polar modifier for butadiene and styrene butadiene polymerization so is to produce rubber. Utilizing the material as an alternative to DTHFP in rubber production avoids subsequent leaching of the DTHFP into the environment as the oligomeric 2, 2-difurylpropane (DTHFP) gives rise to much lower levels of leaching.

COMPLEXES OF IVACAFTOR AND ITS SALTS AND DERIVATIVES, PROCESS FOR THE PREPARATION THEREOF AND PHARMACEUTICAL COMPOSITIONS CONTAINING THEM
Disclosed herein are pharmaceutically acceptable complex formulations comprising complexes of Ivacaftor, or a salt or derivative thereof, together with complexation agents and pharmaceutically acceptable excipients; processes for the preparation thereof; and pharmaceutical compositions containing them. The complexes possess instantaneous redispersibility, increased apparent solubility and permeability compared to KALYDECO, no observable food effect which deliver the opportunity of precise dosing and ease of administration of the reconstituted complex Ivacaftor in solution form.
PRODUCTION OF SALTS OF 4-HYDROXYBUTYRATE USING BIOBASED RAW MATERIALS
Gamma-butyrolactone (GBL) and Gamma-hydroxybutyrate (GHB) having a unique carbon footprint as defined by the percent modern carbon (pmc) are described herein. The percent modern carbon can be controlled by varying the amounts of biobased, renewable starting materials and petroleum-based starting materials to prepare GBL or GHB having a defined pmc or by preparing mixtures of GBL or GHB prepared from biobased renewable starting materials and GBL or GHB prepared from petroleum-based starting materials.
