In heterogeneous catalysis, catalysts provide a surface to which reactants bind in a process of adsorption. The reactant in an enzyme-catalyzed reaction is called a substrate. COA of Formula: C8H5BrS, C8H5BrS. A document type is Patent, introducing its new discovery., COA of Formula: C8H5BrS
The invention provides a preparation method of deuterated aromatic compound. The invention firstly halogenated aromatic compounds and alkali metal salt dissolved in deuterated solvent MA together with conventional solvent or deuterated solvent in the mixed solvent, then drip organosilicon reagent is added, in – 40 C to 150 C under stirring reaction, separation and purification after the reaction, to obtain the deuterated aromatic compound; the method does not require transition metal or metal tin reagent participation, can be efficient, economic, green preparation deuterated aromatic compound, in the preparation of the deuterated product deuterium generation rate greater than 95%. The mild conditions, substrate pervasive is good, high yield, the preparation of the deuterated compounds widely employed in pharmaceutical chemistry and organic chemistry field.
