medicine and materials science, the synthesis of biheteroaryls by cross-coupling remains challenging. We describe here a new, general approach to biheteroaryls: the Ni- and Pd-catalyzed multimetallic cross-Ullmann coupling of heteroaryl halides with triflates. An array of 5-membered, 6-membered, and fused heteroaryl bromides and chlorides, as well as aryltriflates derived from heterocyclic phenols,
Bridged compounds of Formula (I) and Formula (II), pharmaceutical compositions containing them, methods of making them, and methods of using them including methods for treating disease states, disorders, and conditions associated with MGL modulation, such as those associated with pain, psychiatric disorders, neurological disorders (including, but not limited to major depressive disorder, treatment resistant depression, anxious depression, bipolar disorder), cancers and eye conditions.

Provided are a novel triphenyl phosphine derivative synthesized from a triphenylphosphine and a hydroxy-containing lactone; a palladium and a nickel complexes comprising the derivative as a ligand; and a process for preparing a biaryl derivative using the complex as a catalyst. A product can be easily separated from a catalyst or a phosphorus compound, and biaryl derivative can be synthesized in a higher yield, by using the complex of the present invention as a catalyst.
