Pd(OAc)2/1-[2-(di-tert-butylphosphanyl)phenyl]-4-methoxy-piperidine was demonstrated to effectively catalyze cross-coupling of aryl fluoride and aryl(alkyl) titanium reagent. Both electron-deficient and electron-rich aryl fluoride can react effectively with nucleophile and provide extensive functional groups tolerance. 2-Arylated product was realized by selective activation of the C–F bond.

Decarbonylative Phosphorylation of Carboxylic Acids via Redox-Neutral Palladium Catalysis

We describe the direct synthesis of organophosphorus compounds from ubiquitous aryl and vinyl carboxylic acids via decarbonylative palladium catalysis. The catalytic system shows excellent scope and tolerates a wide range of functional groups (>50 examples). The utility of this powerful methodology is highlighted in the late-stage derivatization directly exploiting the presence of the prevalent carboxylic acid functional group. DFT studies provided insight into the origin of high bond activation selectivity and P(O)-H isomerization pathway.
One-step highly selective borylation/Suzuki cross-coupling of two distinct aryl bromides in pure water

A Na2PdCl4-catalysed B2(OH)4-mediated direct cross-coupling of two distinct aryl bromides in pure water is described. This one-step borylation/Suzuki method exhibits an outstanding cross-coupling selectivity and no tendency to produce homocoupling products, therefore leading to biaryls and heterobiaryls in moderate to good yields. Moreover, the reaction has high regio-selectivity and can be scaled-up. Using such a simple, economical and practical protocol, the unsymmetrical diarylation of 3,5-dibromopryidine is achieved.

Disclosed are a carrier for use for separation purpose and a method for separation of a compound which enable a chemical reaction to be performed in a liquid phase, enable a compound of interest to be separated from the liquid phase after the completion of the reaction readily, enable the separated compound to be evaluated by structural analysis or the like while the compound being bound to the carrier, and enable the compound to be separated from the carrier readily. A carrier for separation which has a reaction site capable of reacting with other compound on a benzene ring, and a long-chain group having a specified carbon atom(s) at each of the ortho-position and the para-position of the reaction site through an oxygen atom.

The 1,3-diaminobenzene-derived aminophosphine palladium pincer complex {C6H3[NHP(piperidinyl)2]2Pd(Cl)} - A highly active Suzuki-Miyaura catalyst with excellent functional group tolerance
Bolliger, Jeanne L.,Frech, Christian M.
experimental part, p. 1075 - 1080 (2010/06/17)
The rapidly prepared 1,3-diaminobenzenederived aminophosphine pincer complex {C6H3 [NHP(piperidinyl)2] 2Pd(Cl)} (1) is an effective Suzuki catalyst with excellent functional group tolerance. Side-product formations, such as homocoupling, debromation or protodeboration have only rarely been detected and if so, were in all cases below the 5% level. The presented reaction protocol is universally applicable. Experimental observations indicate that palladium nanoparticles are the catalytically active form of 1.
Novel and potent small-molecule urotensin II receptor agonists
Lehmann, Fredrik,Currier, Erika A.,Clemons, Bryan,Hansen, Lars K.,Olsson, Roger,Hacksell, Uli,Luthman, Kristina

A series of analogs of the non-peptidic urotensin II receptor agonist N-[1-(4-chlorophenyl)-3-(dimethylamino)propyl]-4-phenylbenzamide (FL104) has been synthesized and evaluated pharmacologically. The enantiomers of the two most potent racemic analogues were obtained from the corresponding diastereomeric mandelic amides. In agreement with previously observed SAR, most of the agonist potency resided in the (S) enantiomers. The most potent UII receptor agonist in the new series was (S)-N-[3-dimethylamino-1-(2-naphthyl)propyl]-4-(4-chlorophenyl)benzamide (EC50 = 23 nM at the urotensin II receptor).

Solid-phase Suzuki cross-coupling reactions using a phosphine ligand based on a phospha-adamantane framework
Ohnmacht, Stephan A.,Brenstrum, Tim,Bleicher, Konrad H.,McNulty, James,Capretta, Alfredo
, p. 5661 - 5663 (2007/10/03)
The use of a catalyst system based on Pd2dba3· CHCl3 and 1,3,5,7-tetramethyl-2,4,8-trioxa-6-phenyl-6-phospha- adamantane allows for Suzuki coupling aryl halides with an array of boronic acids on a solid-phase platform. The reactions can be carried out at room temperature with low palladium loadings in high yields.
