C(sp)?C(sp2) bond formation via Sonogashira cross-coupling reactions on 6-halo-2-cyclopropyl-3-(pyridyl-3-ylmethyl)quinazolin-4(3H)-ones with appropriate alkynes was explored. Optimization of reaction conditions with various catalysts, ligands, bases, and solvents was conducted. The combination of PdCl2(MeCN)2 with X-Phos proved to be the best metal?ligand system for this conversion in the presence of triethylamine (Et3N) in tetrahydrofuran at room temperature for iodosubstrates, at 80C for the bromosubstrates in 8 h, and also for the chlorosubstrates in 16 h. We also demonstrated synthesis of a successful diversity-oriented synthesis library of highly functionalized quinazolinones via Cu-free Sonogashira coupling of diverse aryl halides and azido-alkyne (?click?) ligation reactions with substituted azides. The library exhibited significant antimicrobial activity when screened against several microorganisms.

The steric and electronic properties of several sterically demanding tertiary phosphines (dicyclohexylphosphino)biphenyl (2a), 2- dicyclohexylphosphino-2?-methylbiphenyl (2b), 2-dicyclohexylphosphino- 2?,6?-dimethoxybiphenyl (2c), 2-dicyclohexylphosphino-2?, 4?,6?-triisopropylbiphenyl (2d), 2-diphenylphosphino-2?-(N,N- dimethylamino)biphenyl (2e), 2-di-tert-butylphosphino-2?-(N,N- dimethylamino)biphenyl (2f), and di(cyclohexyl)phenylphosphine (2g) have been studied by synthesizing and characterizing iridium complexes of types [IrCl(cod)(L)] (L = 2a-d) and cis-[IrCl(CO)2(L)] (L = 2a-d and 2g). The infrared stretching frequencies of the carbonyl complexes permit an estimation of the ligand donor properties (basicity) and suggest that the donor properties of ligands 2a-d reside between that of 2g and PCy3. The crystal structures of several [IrCl(cod)(L)] (L = 2a-d) and cis-[IrCl(CO) 2(L)] (L = 2a-d and 2g) complexes are reported and used to quantify the ligand steric parameter.

Science experiments are a great way to spark their curiosity, get their minds active, and encourage them to do something that doesn’t involve a screen. 564483-18-7, C33H49P. A document type is Article, introducing its new discovery.

Various monosubstitution and disubstitution patterns on the parent biarylamine skeleton characteristic of palladacycles, as well as the counterion effect, have been studied while looking for ways to increase the effectiveness of the catalyst formed under micellar catalysis conditions in water, with the goal of reducing the amount of Pd needed for coupling reactions. Several substituted palladacycles containing readily accessible ligands were chosen for evaluation. The results indicate that (1) preactivation of Pd(II) salts as precursors for Suzuki-Miyaura (SM) couplings via treatment with a reducing agent is not required; (2) reactions could be performed with approximately half the loading of Pd, relative to that previously required based on a combination of a Pd(II) salt and ligand; and (3) the most effective palladacycle precatalyst has been identified as that containing an isopropyl group on both an aryl ring and on nitrogen, together with the ligand EvanPhos and triflate as the counterion (P13). This precatalyst is also effective in other C-C bond-forming reactions, such as Heck and Sonogashira couplings. No organic solvents were needed for these processes, while the aqueous reaction medium could be recycled several times. A one-pot, four-step sequence involving Suzuki-Miyaura, reduction, alkylation, and acylation reactions highlights the potential for this precatalyst to maximize synthetic gain while minimizing costs and waste generation.
