Aryl Chlorides (aryl + chloride)
Selected AbstractsAn Improved Protocol for Palladium-Catalyzed Alkoxycarbonylations of Aryl Chlorides with Alkyl FormatesADVANCED SYNTHESIS & CATALYSIS (PREVIOUSLY: JOURNAL FUER PRAKTISCHE CHEMIE), Issue 7 2010Thomas Schareina Abstract The palladium-catalyzed alkoxycarbonylation of aryl and heteroaryl halides using butyl formate has been investigated. In the presence of palladium(II) acetate/n -butylbis(1-adamantyl)phosphine (L1), and 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) as base for the first time non-activated chloroarenes can be conveniently carbonylated in good yields. [source] Highly Active, Well-Defined (Cyclopentadiene)(N-heterocyclic carbene)palladium Chloride Complexes for Room-Temperature Suzuki,Miyaura and Buchwald,Hartwig Cross-Coupling Reactions of Aryl Chlorides and Deboronation Homocoupling of Arylboronic AcidsADVANCED SYNTHESIS & CATALYSIS (PREVIOUSLY: JOURNAL FUER PRAKTISCHE CHEMIE), Issue 10 2009Zhong Jin Abstract A new class of well-defined N-heterocyclic carbene (NHC)-(cyclopentadiene)palladium chloride complexes such as CpPd(NHC)Cl wasw synthesized from the readily available starting NHC-palladium(II) chloride dimers. These air-stable, coordinatively saturated NHC-Pd complexes bearing the cyclopentadiene (Cp) unit exhibit high catalytic activity in the room temperature Suzuki,Miyaura and Buchwald,Hartwig cross-coupling reactions involving unactive aryl chlorides as the substrates. In addition, they are found to be extremely efficient catalysts in the deboronation homocoupling of arylboronic acids at room temperature. [source] Increasing the Scope of Palladium-Catalyzed Cyanations of Aryl ChloridesADVANCED SYNTHESIS & CATALYSIS (PREVIOUSLY: JOURNAL FUER PRAKTISCHE CHEMIE), Issue 4 2009Thomas Schareina Abstract An improved protocol for the palladium-catalyzed cyanation of electron-rich aryl chlorides with potassium ferrocyanide {K4[Fe(CN)6]} is presented. Compared to previous procedures the substrate scope is significantly broadened. [source] Palladium-Catalyzed Direct Arylations of 1,2,3-Triazoles with Aryl Chlorides using Conventional HeatingADVANCED SYNTHESIS & CATALYSIS (PREVIOUSLY: JOURNAL FUER PRAKTISCHE CHEMIE), Issue 5 2008Lutz Ackermann Abstract Generally applicable, palladium-catalyzed direct arylations of 1,2,3-triazoles with aryl chlorides were accomplished through conventional heating at reaction temperatures of 105,120,°C. Thereby, intra- and intermolecular CH bond functionalizations were achieved with a variety of differently substituted chlorides as electrophiles, bearing numerous valuable functional groups. [source] Palladium-Catalyzed N -Arylation of N,N -Dialkylhydrazines with Aryl ChloridesADVANCED SYNTHESIS & CATALYSIS (PREVIOUSLY: JOURNAL FUER PRAKTISCHE CHEMIE), Issue 3 2007Sandro Cacchi Abstract N,N -Dialkyl- N, -arylhydrazines have been prepared usually in high to excellent yields via the reaction of N,N -dialkylhydrazines with aryl chlorides in the presence of Pd2(dba)3, Xphos and NaO- t- Bu in dioxane at 120,°C. With ortho -substituted aryl chlorides best results have been obtained by using 2-(2,,6,-dimethoxybiphenyl)dicyclohexylphosphine (ligand d) as the ligand.
