Abstract:
One aspect of the present invention relates to copper-catalyzed carbon-heteroatom and carbon-carbon bond-forming methods. In certain embodiments, the present invention relates to copper-catalyzed methods of forming a carbon-sulfur bond between the sulfur atom of a thiol moiety and the activated carbon of an aryl, heteroaryl, or vinyl halide or sulfonate. In other embodiments, the present invention relates to copper(II)-catalyzed methods of forming a carbon-nitrogen bond between the nitrogen atom of an amide and the activated carbon of an aryl, heteroaryl, or vinyl halide or sulfonate. In certain embodiments, the present invention relates to copper-catalyzed methods of forming a carbon-carbon bond between the carbon atom of cyanide ion and the activated carbon of an aryl, heteroaryl, or vinyl halide or sulfonate. In another embodiment, the present invention relates to a copper-catalyzed method of transforming and aryl, heteroaryl, or vinyl iodide. Yet another embodiment of the present invention relates to a tandem method, which may be practiced in a single reaction vessel, wherein the first step of the method involves the copper-catalyzed formation of an aryl, heteroaryl, or vinyl iodide from the corresponding aryl, heteroaryl, or vinyl chloride or bromide; and the second step of the method involves the copper-catalyzed formation of an aryl, heteroaryl, or vinyl nitrile, amide or sulfide from the aryl, heteroaryl, or vinyl iodide formed in the first step.
Abstract:
The invention relates to polyhalogenated cinnamic acids and cinnamic acid derivatives produced by reacting diazonium salts, which are accessible from polyhalogenated anilines, with acrylic acid or acrylic acid derivatives in the presence of a homogeneous catalyst containing palladium, at temperatures between -5 and +100 DEG C. Part of the cinnamic acids and cinnamic acid derivatives produced in this way is novel. Cinnamic acids and cinnamic acid derivatives produced according to the invention can be used to produce indanones, said indanones constituting precursors for agrochemicals and pharmachemicals and for substances having liquid crystalline properties.
