PHOSPHINE ,FERROCENE ,PALLADIUM compounds - Abstract
The ligand 1,1′-bis(diphenylphosphino)ferrocene (dppf) is commonly employed in a variety of catalytic systems. There are a variety of coordination modes known for dppf, the least studied being the κ
3 coordination mode, in which both phosphorus atoms and the iron atom of dppf interact with another metal center. One such compound is the previously reported [Pd(κ3 -dppf)(PPh3 )]2+ . A series of related compounds, [Pd(κ3 -dppf)(P(p-C6 H4 R)3 )]2+ (R = OCH3 , CH3 , F and CF3 ), has been synthesized and characterized. The X-ray crystal structure of [Pd(dppf)(P(p-C6 H4 F)3 )][BF4 ]2 was determined. Electrochemical and computational studies indicate that the electron donor ability of the P(p-C6 H4 R)3 ligands influences the properties of these compounds. Substitution reactions of the P(p-C6 H4 R)3 ligands have been examined, and, in general, the more electron donating P(p-C6 H4 R)3 ligands completely replace the less electron donating ones. The kinetics of the reaction of [Pd(κ3 -dppf)(P(p-C6 H4 F)3 )]2+ with P(p-C6 H4 OCH3 )3 indicate that the reaction proceeds through a dissociative mechanism, contrary to the associative substitutions prevalent in square planar palladium(ii) chemistry.

- Abstract
The pyran-opyran amide (2 S ,4a R ,8a R )-6-oxo-2,4a,6,8a-tetra-hydro-pyrano[3,2- b ]pyran-2-carboxamide, C
9 H9 NO4 , 3 , was prepared by a chemoselective hydration of the corresponding nitrile, 2 , using a heterogeneous catalytic method based on copper(II) supported on mol-ecular sieves, in the presence of acetaldoxime. Compound 3 belongs to a new class of pyran-opyrans that possess anti-bacterial and phytotoxic activity. Crystallographic analysis of 3 shows a bent structure for the cis -fused bicyclic pyran-opyran, similar to nitrile 2 . Evidence of an intra-molecular hydrogen bond involving the amide group and ring oxygen was not observed; however, two separate inter-molecular hydrogen-bonding inter-actions were observed between the amide hydrogen atoms and adjacent carbonyl oxygen atoms along the b - and a -axis directions. The latter inter-action may also be supported by an inter-molecular C-H⋯O hydrogen bond. The lattice is filled out by close-packed layers of this hydrogen-bonded network along the c- axis direction, related from one to the next by a 21 screw axis., (© Greene et al. 2020.)- Published

- Abstract
Chemomechanical reaction: The first octahedral ruthenium bipyridine complex that bears six polymerizable vinyl groups is used as an active cross-linker. It is a key building block for cross-linked polymeric networks (right) thus allowing the construction of molecular architectures in chemomechanical soft materials., (Copyright © 2013 WILEY-VCH Verlag GmbH & Co.
