摘要:
Methods for separating and purifying carbon nanomaterials such as trimetallic nitride endohedral metallofullerenes are described. In certain embodiments, carbon nanomaterials are contacted with a carbon nanomaterial reactive agent. The reactive agent binds empty cage fullerenes, nanotubes, and endohedral metallofullerenes without appreciably binding trimetallic nitride endohedral metallofullerenes. According to some embodiments, purified forms of trimetallic nitride endohedral metallofullerenes may be prepared.
摘要:
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.

摘要:
Aminostyrylanthracene compounds of the general formula [I] [wherein R is unsubstituted aryl; R is aryl which may be substituted with one or more members selected from among various groups; and R to R are each hydrogen, cyano, hydrocarbyl, or the like]. These compounds can be prepared by condensing the corresponding aminobenzaldehydes with the corresponding phosphonic esters or phosphonium salts.
