A general and efficient catalyst for palladium-catalyzed C-O coupling reactions of aryl halides with primary alcohols.

J. Am. Chem. Soc. 132 , 11592, (2010)

An efficient procedure for palladium-catalyzed coupling reactions of (hetero)aryl bromides and chlorides with primary aliphatic alcohols has been developed. Key to the success is the synthesis and exploitation of the novel bulky di-1-adamantyl-substituted bip...

A general method for the synthesis of unsymmetrically substituted ureas via palladium-catalyzed amidation.

Org. Lett. 11 , 947, (2009)

A general and practical method for the preparation of unsymmetrically substituted ureas has been developed utilizing palladium-catalyzed amidation. Both aryl bromides and chlorides, as well as heteroaryl chlorides, have been coupled to aryl, benzyl, and aliph...

Palladium-catalyzed coupling of hydroxylamines with aryl bromides, chlorides, and iodides.

Org. Lett. 11 , 233, (2009)

The bis-pyrazole phosphine ligand BippyPhos is effective for the palladium-catalyzed cross-coupling of hydroxylamines with aryl bromides, chlorides, and iodides. Reactions proceed smoothly at 80 degrees C in toluene in the presence of Cs(2)CO(3) to give synth...
