标题:Process for the synthesis of isocyanates and of isocyanate derivatives

摘要:The present invention relates to a process for the synthesis of isocyanates and of isocyanate derivatives. Isocyanates are obtained by reacting an organic halide with a metal cyanate in an organic medium in the presence of a catalyst consisting of a complex of nickel with at least one organic ligand, in which complex the nickel is in the zero oxidation state. A carbamate or a urea, respectively, are obtained by a subsequent reaction with a hydroxy compound or a primary or secondary amine. Isocyanates and their derivatives are used especially either as refined synthesis agents for the production of pesticides and medications, or as monomers or comonomers for the preparation of many macromolecular compounds.

标题 :One-pot synthesis of group 8 transition metal carbene complexes useful as olefin metathesis catalysts

摘要:The invention provides a novel method for synthesizing transition metal carbene complexes useful as olefin metathesis catalysts. The method is a convenient one-pot synthesis in which transition metal carbenes are prepared in high yield from readily available starting materials via a dihydrogen complex containing two different anionic ligands, preferably a phosphine and a heteroatom-stabilized carbene. The invention additionally provides a method for synthesizing precursors to carbene ligands useful, inter alia, in the aforementioned one-pot synthesis. The precursors are in the form of trichloromethyl adducts of the formula L 1 -CCl 3 , where L 1 is a heteroatom-stabilized carbene ligand, and are prepared by contacting an unsaturated, ionized analog of L-CCl 3 with a non-nucleophilic base in the presence of chloroform.

摘要:The present application relates to the field of organic synthesis. Provided is a condensing agent. The condensing agent has formula 1, wherein R1 and R2 are each independently selected from the same or different electron-withdrawing groups. Compared with thiophosgene or carbon disulfide used in a traditional solution, the condensing agent provided in the embodiments of the present application has lower toxicity, and the condensing agent is a solid, such that the diffusion of pollution is easily controlled. Therefore, the condensing agent provided in the embodiments of the present application can be used for environmentally friendly synthesis of an isothiocyanate compound and has relatively small influence on the environment. Moreover, the condensing agent provided in the embodiments of the present application comprises electron-withdrawing groups, such that the yield of the isothiocyanate compound can be increased.
