摘要:A multidentate phosphite ligand is used in the catalytic synthesis of adiponitrile. The ligand is represented by the following general formula (I). The method of catalytic synthesis of adiponitrile comprises primary hydrocyanation, isomerization, and secondary hydrocyanation reactions, wherein the catalyst adopted each comprises a phosphite ligand-nickel complex composed of a nickel precursor and a multidentate phosphite ligand. The ligand molecule has a higher electron cloud density, and the phosphorus content capable of participating in coordination in the ligand molecule per unit mass is higher, so that the catalytic activity of the catalyst is improved, and the amount of the catalyst is reduced.

摘要:A method for the combined synthesis of a mono-unsaturated nitrile-ester(acid) and of a bi-functional carbonyl compound, wherein it includes a step including the cross metathesis mc1 of an unsaturated fatty acid/ester compound with an unsaturated nitrile compound, in which mc1 is performed with partial conversion such as to obtain and recover, separately, at least the following products: a mono-unsaturated nitrile-ester/acid and a symmetrical compound, diester or diacid respectively including a double bond located in the middle of the molecular chain of compound, and subsequently a step including the oxidation cleavage cp2 of the double bond of compound, such as to form a single type of carbonyl compound having formula R2-(CH2)n-COR′, in which R′ is H or OH, depending on the operating conditions selected for the oxidation cleavage cp2. Also, the production of monomers for the polymer industry.

发明人：BRYNDZA HENRY E
权利人:DU PONT
摘要:An improved process for the synthesis of zerovalent nickel catalyst useful for the hydrocyanation of olefins, wherein catalyst formation is improved by applying sonication during formation of catalyst. The sonication may be applied to the catalyst reactant mixture containing elemental nickel and a ligand; or alternatively, the sonication may be applied to the elemental nickel prior to the addition of ligand to the reaction mixture.

摘要:Embodiments of the present application relate to the preparation of 2′-O-protected nucleoside phosphoramidites and conjugation of the 2′-O-protected nucleoside to a solid support. More specifically, the present application relates to nucleosides having a hydroxy protecting group at the 2′ position that reduces migration to the 3′ position during RNA (e.g., mRNA) synthesis and can be readily removed under mild conditions without the use of toxic metal-containing reagents. Methods of using the nucleosides described herein in RNA synthesis are also disclosed.
