Continuous-Flow Synthesis of Biaryls by Negishi Cross-Coupling of Fluoro- and Trifluoromethyl-Substituted (Hetero)arenes

A continuous-flow method for the regioselective arylation of fluoroarenes and fluoropyridines has been developed. The telescoped procedure reported here consists of a three-step metalation, zincation, and Negishi cross-coupling sequence, providing efficient access to a variety of functionalized 2-fluorobiaryl products. Precise temperature control of the metalation step, made possible by continuous-flow technology, allowed for the efficient preparation of the arylated products in high yields and short residence times. Additionally, several examples of the regioselective arylation of benzotrifluoride derivatives are also provided.

Syntheses with organoboranes. XIII. Synthesis of omega-(4-bromophenyl)alkanoic acids and their borylation

omega-(4-Bromophenyl)alkanoic acids 2c-e were obtained from 1-bromo-4-alkenylbenzenes 5c-e by hydroboration-thermal isomerization-oxidation. Their esters 11c-e were transformed in good yields into the corresponding boronates 12c-e by the cross-coupling reaction with (10) in an ionic liquid, [bmim][BF4]. The use of pinacolborane for the coupling reaction in the ionic liquid gave debromination products, and low yields of 12c-e.

95464-05-4, Name is 1,1′-Bis(diphenylphosphino)ferrocene-palladium(II)dichloride dichloromethane complex, belongs to catalyst-palladium compound, is a common compound. Formula: C35H32Cl4FeP2PdIn an article, once mentioned the new application about 95464-05-4.

Wide bite angle diphosphine ligands were used to prepare [(diphosphine)M(2-(diphenylphosphino)pyridine)]2+ complexes (M = Pd, Pt). Except for the ligand with the largest bite angle, 2-(diphenylphosphino) pyridine coordinates in a bidentate mode leading to bis-chelate complexes. In the case of Xantphos (9,9-dimethyl-4,5-bis(diphenylphosphino)-xanthene, betan = 111) two types of complexes are formed, in which 2-(diphenylphosphino)pyridine coordinates in a mono- or bidentate fashion, respectively. The crystal structures of three of the Pt complexes were determined. The X-ray crystal structure of [(Xantphos)-Pt(2-(diphenylphosphino) pyridine)]2+ shows that Xantphos coordinates in a tridentate P,O,P fashion. Under dihydrogen pressure, the pyridyl moiety in the platinum complexes can de-coordinate to provide a vacant coordination site at the metal center. Furthermore it can act as an internal base to assist the heterolytic cleavage of dihydrogen. The reaction yields a platinum hydride with a protonated pyridine moiety in close proximity to one another. The structure as well as the reactivity of the complexes towards dihydrogen is governed by the steric requirements of the diphosphines. The crystal structure of [(dppf)PtH(2- (diphenylphosphino)pyridinium)](OTf)2 has been determined. Palladium complexes containing DPEphos or Xantphos decompose under dihydrogen pressure. In the case of dppf slow heterolytic splitting of dihydrogen occurs to form the hydride complex [(dppf)PdH(2-(diphenylphosphino)pyridinium)](OTf)2 which contains a protonated 2-(diphenylphosphino)pyridine ligand. In solution, this compound slowly undergoes P-C bond cleavage of the 2-(diphenylphosphino) pyridine ligand to form [(dppf)Pd(PHPh2)(eta1-C 5H4NH)](OTf)2. When the 6-methyl-2- pyridyldiphenylphosphine ligand is used, the reaction of the palladium complex with dihydrogen is very fast and the hydride complex immediately rearranges to the diphenylphosphino compound resulting from P-C bond cleavage.

Diorganyl tellurides as substrates in Sonogashira coupling reactions under mild conditions

A new method of Sonogashira coupling reactions between diorganyl tellurides and terminal alkynes is reported. The coupling reactions are performed using Pd(dppf)Cl2 as a catalyst, CuI as a co-catalyst in the presence of K2CO3 in DMSO. The reactions are carried out at room temperature and completed within 2 h when phenyl acetylene is used as a terminal alkyne. For aliphatic terminal alkynes, such as 1-hexyne and 1-octyne, an elevated temperature and longer reaction time are needed for the completion of the reactions. This process results in good yields of Sonogashira coupling products which is applicable for diaryl, divinyl and dialkynyl tellurides but not applicable for dialkyl tellurides.
