摘要:
Objects of the present invention are to provide a novel niobium or tantalum complex having good vapor pressure and becoming a raw material for producing a niobium- or tantalum-containing thin film by a method such as CVD method, ALD method or the like, a method for producing the same, a metal-containing thin film using the same, and a method for producing the same. The present invention relates to producing an imide complex represented by the general formula (1) by, for example, the reaction between M 1 (NR 1 )X 3 (L) r (2) and an alkali metal alkoxide (3):
(wherein M 1 represents niobium atom or tantalum atom, R 1 represents an alkyl group having from 1 to 12 carbon atoms, R 2 represents an alkyl group having from 2 to 13 carbon atoms, X represents halogen atom, r is 1 when L is 1,2-dimethoxyethane ligand, r is 2 when L is pyridine ligand, and M 2 represents an alkali metal), and producing a niobium- or tantalum-containing thin film by using the imide complex (1) as a raw material.
摘要:
In a process for producing 1-substituted-3-fluoroalkyl-pyrazole-4-carboxylate (3) by a reaction of 2-alkoxymethylenefluoroacylacetate (1) and hydrazine (2), the reaction is conducted in the presence of a base and water, to produce 1-substituted-3-fluoroalkylpyrazole-4-carboxylate (3) with high selectivity and yield. This novel process enables to produce 1-substituted-3-fluoroalkylpyrazole-4-carboxylate (3), which is useful as an intermediate for pharmaceuticals and agrochemicals, with high selectivity and yield by simple and safe operations.

摘要:
The invention provides human proteins having secretory signal sequences and DNAs coding for these proteins as well as eucaryotic cells forming said proteins by secretory expression. All of the proteins are secreted outside the cells and exist in the extracellular liquid or on the cell membrane, so that they are considered to be proteins controlling the proliferation and the differentiation of the cells. Accordingly, the proteins can be employed as pharmaceuticals or as antigens for preparing antibodies against said proteins. Furthermore, said DNAs can be utilized for expression of said proteins in large amounts. Eucaryotic cells wherein expression vectors of said cDNAs are introduced can be utilized for secretory production of the proteins encoded by said cDNAs.
