In heterogeneous catalysis, the catalyst is in a different phase from the reactants. Product Details of 89089-18-9, At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 89089-18-9, name is 3-Bromo-6-chloropyridazine. In an article，Which mentioned a new discovery about 89089-18-9
Disclosed is a dehydrohalogenation method in which a halogen atom on a carbon atom in an organic compound is removed by substituting the halogen atom by a hydrogen atom. Also disclosed is a process for production of a dehalogenated compound. The dehydrohalogenation method comprises the step of treating an organic compound having a halogen atom on a carbon atom therein with a compound represented by the formula (2-1): M2BHpR1 q (2-1) or the formula (2-2): M3(BHpR1 q)2 (2-2) wherein M2 represents an alkali metal atom; M3 represents a alkali earth metal atom or a zinc atom; R1 represents a hydrogen atom, a cyano group, an acyloxy group having 2 to 13 carbon atoms or an alkoxy group having 1 to 6 carbon atoms; p represents an integer of 1 to 4; and q represents an integer of 0 to 3, provided that the sum total of p and q is 4 in a solvent in the presence of a complex of a metal belonging to Group VIII represented by the formula (1): M1XmLn (1) wherein M1 represents a metal belonging to Group VIII; X represents a halogen atom; L represents a neutral ligand; m represents an integer of 1 to 2; and n represents an integer of 2 to 3, provided that the sum total of m and n is 4.
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 89089-18-9, help many people in the next few years.Product Details of 89089-18-9
