Current efforts in this laboratory continue to focus on the preparation of novel complexant motifs for potential use in chemoselective minor-actinide liquid?liquid separations of relevant cations from used nuclear fuel. The present work describes an efficient Pd-catalyzed amination reaction of diversely functionalized 6-bromo-1,2,4-triazinyl-pyridine scaffolds with various amines to afford the opportunity for convergent modulation of complexant electronic and steric properties directly from one substrate towards potentially enhanced solubility in process-relevant solvents. The 21 novel examples presented highlight a unified approach to extensive molecular diversity and provide the ability to further study chelate effects, solubility properties, and complexation efficacy on nonsymmetric, moderately soft-Lewis-basic complexant scaffolds without the incorporation of additional heteroaromatic moieties. Synthetic-method optimization, amine and scaffold scope, as well as a scale-up experiment are presented.

A new PCcarbeneS ligand has been designed to stabilize late transition metal carbene complexes with Schrock-type reactivity for bond activations via metal-ligand cooperation. This ligand combines previous approaches to such complexes by stabilizing the carbene moiety through either charge delocalization into adjacent aryl groups or the use of an anion-stabilizing substituent. Nickel and palladium complexes of the PCcarbeneS pincer ligand could be prepared by dehydrohalogenation of the precursors (PCsp3S)NiCl and (PCsp3S)PdCl and were characterized in solution and solid state. X-ray diffraction (XRD) analyses as well as density functional theory (DFT) studies demonstrate that the electronic structure of these complexes can be described by a carbene as well as a zwitterionic complex with a M-C single bond. Due to the strong nucleophilic character at the carbon atom, both complexes are highly reactive and undergo sulfur transfer to form thioketone complexes. The nickel carbene complex is capable of cooperative O-H and N-H bond activations including ammonia activation across the Nia? C bond.

Highly regio- and stereoselective borylstannylative carbocyclization of diynes 2a-f with the borylstannane 1 are efficiently catalyzed at room temperature by a series of palladium complexes such as Cl2Pd(PPh3)2, Cl2Pd[P(o-tolyl)3]2, Pd(PPh3)4, and Pd-(dba)2, giving 1-(borylmethylidene)-2-(stannylmethylidene)cycloalkane derivatives 3a-f in high yields. A 1,6-enyne (2g) also reacts similarly to afford a high yield of the corresponding cyclized product 3g.

A new palladium nanoparticle catalyst on mesoporous silica prepared from a molecular cluster precursor

A promising approach to the controlled synthesis of supported nanoparticles involves the use of molecular carbonyl clusters as precursors. Molecular metal clusters consist of a defined number of structurally ordered atoms, and active monodisperse metal particles are formed after dispersing the molecules and removing the ligands. An octanuclear palladium cluster precursor with easily displaceable ligands was used to generate palladium nanoparticles on mesoporous MCM-41. The molecular cluster precursor, [Pd8(CO) 8(PMe3)7], was directly adsorbed from solution onto MCM-41, followed by gentle thermolysis which yielded small metal nanoparticles. Compared to MCM-41-based catalysts prepared from palladium salts by conventional methods, this cluster-derived palladium catalyst has shown an efficient activity for liquid-phase hydrogenation of alkenes.
