C–H functionalization of benzyl electrophiles with nucleophiles via palladium-catalyzed benzylic C–N cleavage. A range of N-(1-naphthylmethyl)sulfonimides, N-(2-thienylmethyl)sulfonimides, and N-(2-furanylmethyl)sulfonimides smoothly underwent palladium-catalyzed aromatic C–H allylation with allyl Grignard reagents at roomtemperature, delivering structurally diverse substituted 1-allylnaphthalenes and

The invention also provides methods for the treatment and prevention of neurological disorders, such as neuropsychiatric and neurodegenerative diseases, as well as pain, ataxia and convulsion. The compounds of the invention have the general structure:
wherein A is NH or S. Q is a member selected from CR1 and N. X and Y are members independently selected from O, S, CR2, N and NH. R1, R2 and R4 are members independently selected from H and F, provided that at least one member selected from R1, R2 and R4 is F. R6 is a member selected from O−X+ and OH, wherein X+ is a positive ion, which is a member selected from inorganic positive ions and organic positive ions.
This invention provides fused heterocycles having the formula:
in which R1 is a member selected from the group consisting of H, substituted or unsubstituted arylalkyl and substituted or unsubstituted heteroarylalkyl. R2 is a member selected from the group consisting of H substituted or unsubstituted alkenyl, substituted or unsubstituted arylalkyl and substituted or unsubstituted heteroarylalkyl. R3is a member selected from the group consisting of H, C1-C6 substituted or unsubstituted alkyl, substituted or unsubstituted arylalkyl and substituted or unsubstituted heteroarylalkyl. R4 is a member selected from OH and O−X+, in which X+ is positive ion which is a member selected from organic positive ions and inorganic positive ions. Substituted or unsubstituted arylalkyl and substituted or unsubstituted heteroarylalkyl moieties have the formula:
in which Ar is a member selected from the group consisting of substituted or unsubstituted aryl and substituted or unsubstituted heteroaryl. The index n is an integer from 1 to 4.
