摘要:A ruthenium-phosphine complex can be used as a catalyst in a method for the catalytic synthesis of urea. The method may comprise more particularly a reaction of formamide or of formamide with ammonia in the presence of the catalyst to form urea and hydrogen. Through the use of the ruthenium-phosphine complex as the catalyst, catalytic preparation of urea from formamide or from formamide with ammonia is provided for the first time. This allows for synthesis under mild conditions and virtually no formation of byproducts. Further, using an acid as a cocatalyst in the catalytic synthesis or the reaction can lead to an improvement in urea yield.

摘要:This invention relates to thermoplastic elastomeric polyolefin alloys (preferably polypropylene alloys) and the processes for preparing naturally compatibilized polyolefin alloys using a 'one-pot' polymerization of a single monomer (preferably propylene), whereby two homopolymers having different stereoisomeric structures are produced (preferably stereoregular and stereoirregular), as well as a third block copolymer having alternating sequences of the two structural segments of the two homopolymers; and wherein catalyst compositions are used enabling the direct synthesis of naturally compatibilized polymer blends comprising for components: two organometallic complexes of group IVB elements, a catalyst which irreversibly reacts with at least one ligand on the transition metal complexes converting it to catalytically active state, and a hydrocarbyl, substituted hydrocarbyl, or oxyhydrocarbyl compound of Group IIA, IIB, and IIIA metals, which functions as a cross-over agent.

摘要:Disclosed in the present invention are a synthesis method and application of a benzoselenazole-1-ketone compound and a derivative thereof. Sulfoximine and the element selenium are used as raw materials, and by means of a rhodium catalysis direct C-H functionalization reaction, synthesis of a series of benzoselenazole-1-ketone compounds is achieved. The solution has the advantages of strong functional group compatibility, wide substrate universality, mild conditions, simple operations, and high efficiency and universality. Meanwhile, sulfoximine and the element selenium are used as initial raw materials, a direct C-H functionalization reaction is carried out, and by means of chiral phosphoric acid, synthesis of the chiral benzoselenazole-1-ketone compound is achieved. The application prospect is good, and a sulfydryl structure in biomacromolecules such as polypeptides, saccharides, drug molecules and proteins can be specifically marked. Good anti-SARS-CoV-2 virus activity is exhibited, a trastuzumab biological conjugate can effectively image HER 2 receptors on the cell surface, displays strong fluorescence, and can be applied to the preparation of an imaging reagent for the HER 2 receptor on the cell surface.
