A novel method for Pd-catalyzed triflination of aryl and heteroaryl triflates using NaSO2CF3 as the nucleophile is described. The combination of Pd2(dba)3 and RockPhos formed the most effective catalyst. A broad range of functional groups and heteroaromatic compounds were tolerated under the neutral reaction conditions. The order of reactivity ArOTf ? ArCl ? ArBr is consistent with transmetalation being a slow step of the reaction.

The answer is in thermodynamics and kinetics.In a document type is Article, and a compound is mentioned, 14220-64-5, Bis(benzonitrile)palladium chloride, introducing its new discovery.

fac-[ReBr(CO)3(L1,2)] L1 = 1-ethyl-2-(pyridin-2-yl)benzimidazole (1) and L2 = 1-[(pyridin-2-yl) benzimidazole]-propyl-sulfonic acid (2), fac-[Re2Br2(CO)6L3] (3) L3 = 1,1?-(hexane-1,6-diyl)bis[2-(pyridin-2-yl)1H-benzimidazole] and fac-[ReBr(CO)3(L4,5-kappa2N1N2)] (L4 = 2,6-bis(benzimidazol-2?-yl)pyridine (4) and L5 = 2,6-bis(1-ethyl-benzimidazol-2?-yl)pyridine (5) were synthesized and fully characterized using different spectrocopic and analytical tools. The spectrocopic data showed coordination of L1-3 to fac-ReBr(CO)3via the benzimidazole and pyridine N-atoms. For 4 and 5, the absence of a two-fold axis of symmetry for L4,5 in the 1H NMR spectra reflect the kappa2N1,N2 mode of coordination. The electronic properties of 1-5 were investigated by time-dependent density functional theory calculations in the singlet and triplet states. The ligands and their Re(i) complexes were assessed for their potential antimicrobial activity. Compound 5 was screened against non-malignant cell line (noncancerous human embryonic kidney cell line (HEK293)) as well as evaluated for its blood compatibility.

Oxidative carbonylation of alkynes can be carried out catalytically in the absence of added oxidants if it is coupled with a reductive carbonylation process at the expense of the same alkyne involved in the oxidative process.Maleic esters (from oxidative carbonylation) and unsaturated lactones (from reductive carbonylation) are the main products formed under the catalytic action of palladium iodide complexes with thiourea (tu).A complex, formally corresponding to the ionic formula I, allows the reaction of alkylacetylenes at room temperature and atmospheric pressure.With activated alkynes such as phenylacetylene, or with alkynes containing coordinating groups, other palladium complexes with two or four molecules of thiourea are also active, although to a lesser extent.Identification of the organic by-products gives a hint of the mechanism by which coupling of oxidative and reductive carbonylation occurs.Keywords: Palladium; Alkynes; Oxidative carbonylation; Reductive carbonylation; Catalysis, Thiourea
