4,4?-bipyridine-N-monoxide. A hybrid ligand for building networks using a combination of metal-ligand and hydrogen-bonding interactions

The ligand 4,4?-bipyridine-N-monoxide, (BIPYMO) coordinates through the pyridine N-donor to Pt(ii) and Pd(ii) to form square planar [ML 4]2+ complexes and to Cu(ii) and Zn(ii) to form octahedral trans-[M(H2O)2L4]2+ complexes. Single crystal X-ray structures show that these individual building blocks are organized via hydrogen bonding through the external N-oxide O-atoms to form 2D and 3D networks.

Synthesis, characterization and protonation reaction of copper and palladium complexes bearing nitrite ligands in O,O-bidentate and N-monodentate bonding fashions

Cu(Ph2P(o-C6H4C(O)H))2(NO 2) (3) has been prepared in high yield by treating [Cu(Ph 2P(o-C6H4C(O)H))2(NCMe)]BF 4 (2) with [Ph2PNPPh2]NO2 at ambient temperature. The nitrite ligand of 3 is coordinated to the Cu(I) center in an O,O-bidentate mode. Protonation of 3 releases NO molecule, which mimics the reactivity of the Type 2 Cu-NiRs. In contrast, reaction of [Pd(NCMe) 4](BF4)2 and Ph2P(o-C 6H4C(O)H) affords cis-[Pd(Ph2P(o-C 6H4C(O)H))2](BF4)2 (4) with the Pd2+ ion chelated by two phosphino-aldehyde moieties. The hemilabile formyl ligands of 4 can be displaced by NO2- to produce trans-Pd(Ph2P(o-C6H4C(O)H)) 2(NO2)2 (5), of which the nitrite ligands present an N-monodentate bonding feature. Protonation of 5 with HBF4, however, regenerates compound 4, likely via elimination of nitrous acid. The structures of 3-5 have been determined by an X-ray diffraction study.

Practical Synthesis of Chromeno[2,3-b]indole Skeleton via an Aldehyde Group Insertion/Aromatization Strategy

The synthesis of chromeno[2,3-b]indole from simple starting materials remains a demanding process. Herein, 2-bromoindole undergoes nucleophilic attack from salicylaldehyde, followed by intramolecular insertion of an aldehyde group and aromatization to generate the desired chromeno[2,3-b]indoles. Moreover, various functional groups were tolerated and a gram-scale synthesis of the product could be achieved under the optimized condition.

A photoinduced Wolff rearrangement/Pd-catalyzed [3+2] cycloaddition sequence: An unexpected route to tetrahydrofurans

A novel sequential reaction that combines a visible light-induced Wolff rearrangement of alpha-diazoketones and a Pd-catalyzed [3+2] cycloaddition of vinyl cyclopropanes with the resulting ketenes is described in this work. Selective O-allylic alkylation was observed over C-allylic alkylation, which unexpectedly led to a series of highly functionalized tetrahydrofurans with high efficiency (20 examples, 58-99% yields).

Efficient Pd-Catalyzed Allene Synthesis from Alkynes and Aryl Bromides through an Intramolecular Base-Assisted Deprotonation (iBAD) Mechanism

An optimized ligand-controlled palladium-catalyzed allene synthesis starting from alkynes and aryl bromides giving rise to allene products in a simple and direct manner is described. The methodology is performed in an inter- and intramolecular fashion with unprecedented scope and excellent yields. Based on mechanistic investigations and on DFT calculations, the role played by the carboxylic additive (i.e., PivOH) in controlling the selectivity of the reaction is discussed, allowing us to propose an intramolecular base-assisted deprotonation (iBAD) mechanism for this process.

Indirect ortho functionalization of substituted toluenes through ortho olefination of N,N-dimethylbenzylamines tuned by the acidity of reaction conditions

Highly regioselective olefination of substituted N,N-dimethylbenzylamines was developed by tuning the acidity of reaction conditions based on analysis of their features. The ortho-functionalized N,N-dimethylbenzylamines were further transformed into 3-(2?-tolyl)propanoic acid and its derivatives under mild conditions. These two transformations could be combined into one pot, and 3-(2?-tolyl)propanoic acid and its derivatives were obtained in moderate to good yields. Mechanistic studies indicated that electrophilic attack on the phenyl ring by the Pd(II) ion assisted by the N,N-dimethylaminomethyl group was a key step during this catalytic transformation, which was controlled by the acidity of the reaction conditions.

Synthesis, characterization, and reactivity of monomeric, arylpalladium halide complexes with a hindered phosphine as the only dative ligand

We report the isolation and structural characterization of several monomeric arylpalladium(II) halide complexes containing tri-tert-butyl phosphine, 1-adamantyl-di-tert-butylphosphine, or 2-adamantyl-di-tert-butylphosphine. X-ray diffraction, IR spectroscopy, and theoretical studies indicated that the complexes may be stabilized by agostic interactions. For example, the distance from the closest hydrogen atom to the palladium metal center in the X-ray structure of the 1-adamantyl-phenylpalladium bromide complex 1 was 2.26(3) A. The calculated Pd-H distance of 2.28 A and harmonic vibrational frequencies were in agreement with the measured distance, but Wiberg bond indices indicated only weak M-H-C interactions. Addition of 2-adamantyl-di-tert-butyl phosphine to 1 led to ligand exchange and formation of 2-adamantyl-di-tert-butyl phosphine complex 2. Addition of P(t-Bu)3 generated free aryl bromide and Pd[P(t-Bu)3]2. Reactivity of complex 1 with nucleophiles provided evidence of the intermediacy of these complexes in palladium-catalyzed cross-coupling reactions. Complex 1 reacted with amine and base to form the corresponding arylamine, with tert-butoxide to form the corresponding ether, with boronic acid and fluoride to form the corresponding biaryl, and with styrene to form stilbene. This complex also catalyzed the reaction of bromobenzene with diphenylamine in the presence of base to produce 94% of the amination product in 45 min at room temperature. This rate is comparable to the reaction rate of in situ generated catalysts. Copyright
