A novel heterobimetallic complex composed of the imide-bridged [3]ferrocenophane and the tridentate palladium(II) complex

New 1,1’-Ferrocene Bis(sulfonyl) Reagents

“…Due to the number of atoms involved in the bridge and the length of both the S−C and S−N bonds, there is little strain in this ferrocenophane, and the Cp rings have a dihedral angle of 11.6°. The structure of previously reported 2‐benzylidene [3]ferrocenophane‐1,3‐dione exhibited a ∼14° dihedral angle between Cp rings while Hirao observed larger tilt angles around ∼16° in the imide‐bridged [3]ferrocenophane compounds . The S−N bonds measure 1.6807(13) and 1.6854(12) Å and the S−N‐S bond angle is 121.37(7)°.…”

“…However in the case of glycine methyl ester, we observed the formation of a [3]ferrocenophane, compound 5 . Ferrocenophanes have been reported using a variety of bridging groups to link the two cyclopentadienyl rings . We were able to fully characterize this compound, including via single crystal X‐ray methods, as shown in Figure .…”

Cyclopalladated complexes with N-(benzoyl)-N′-(2,4-dimethoxybenzylidene)hydrazine: syntheses, characterization and structural studies

“…The Pd-Cl bond lengths observed in 3 and 6 are within the range reported for ortho-palladated species [12,16,[35][36][37][38] having the Cl-atom at the trans position with respect to the metallated C-atom. The Pd-N(3) [23,39], Pd-P [16][17][18]31] and Pd-S [40] bond lengths in 3, 4 and 6, respectively are unexceptional.…”

Simultaneous Identification of Neutral and Anionic Species in Complex Mixtures without Separation

“…The complexes are synthesized with a weakly bound acetonitrile that is rapidly replaced by stronger ligands such as pyridine. [8] The wide analyte scope provided by this motif allows for the simultaneous detection of multiple species. As a result of the well-defined coordination chemistry displayed by these complexes, they have been investigated as recognition elements for chemical warfare agents and used to construct functional molecular assemblies.…”

“…[7] Another appealing feature of these complexes is the ability to undergo facile ligand exchange at only one coordination site, but also exhibit analyte bound complexes that are static on the NMR timescale.T he complexes are synthesized with aw eakly bound acetonitrile that is rapidly replaced by stronger ligands such as pyridine. [8] Thew ide analyte scope provided by this motif allows for the simultaneous detection of multiple species.A saresult of the well-defined coordination chemistry displayed by these complexes,they have been investigated as recognition elements for chemical warfare agents and used to construct functional molecular assemblies. [9] Furthermore,w eh ave shown that chiral fluorinated palladium pincer complexes are capable of differentiating pairs of enantiomeric amines in complex mixtures.…”
