Structures and Solvatochromic Phosphorescence of Dicationic Terpyridyl–Platinum(II) Complexes with Foldable Oligo(ortho‐phenyleneethynylene) Bridging Ligands
Authors: Zhu Ming‐Xin , Lu Wei , Zhu Nianyong , Che Chi‐Ming 
Published: September 2008

AbstractA series of binuclear organoplatinum(II) complexes, [(tBu3tpy)Pt(CC1,2‐C6H4)nCCPt(tBu3tpy)][ClO4]2 (1–7, n=1, 2, 3, 4, 5, 6, 8; tBu3tpy=4,4′,4′′‐tri‐tert‐butyl‐2,2′:6′,2′′‐terpyridine) with foldable oligo(ortho‐phenyleneethynylene) linkers were prepared and characterized by spectroscopic methods and/or X‐ray crystallographic analyses. In the crystal structures of 3⋅2.5 CH3OH, 5⋅CH3CN, and 6⋅4 CH3CN, each of the bridging ortho‐phenyleneethynylene ligands has a partially folded conformation. In aerated water/acetonitrile mixtures with water percentages larger than 40 %, the emission of complexes 3–7 are red‐shifted and enhanced when compared to those recorded in acetonitrile. The red‐shift in emission energy and enhanced emission intensity can be attributed to the inter‐ and/or intramolecular interactions induced by the addition of water to solutions of the platinum(II) complexes in acetonitrile. Data from dynamic light scattering and transmission electron microscopy studies revealed that these binuclear platinum(II) complexes aggregated into nanosized particles in acetonitrile/water mixtures. Hydrophobic folding of the ortho‐phenyleneethynylene linkers in acetonitrile/water mixtures is postulated.
Protein Nanotubes Comprised of an Alternate Layer‐by‐Layer Assembly Using a Polycation as an Electrostatic Glue

Published: September 2008

AbstractWe present the synthesis and structure of various protein nanotubes comprised of an alternate layer‐by‐layer (LbL) assembly using a polycation as an electrostatic glue. The nanotubes were fabricated by sequential LbL depositions of positively charged polycations and negatively charged proteins into a porous polycarbonate (PC) membrane, followed by release of the cylindrical core by quick dissolution of the template with CH2Cl2. This procedure provides a variety of protein nanotubes without interlayer cross‐linking. The three‐cycle depositions of poly‐L‐arginine (PLA) and human serum albumin (HSA, Mw=66.5 kDa) into the porous PC template (pore diameter, Dp=400 nm) yielded well‐defined (PLA/HSA)3 nanotubes with an outer diameter of 419±29 nm and a wall thickness of 46±8 nm, revealed by scanning electron microscopy (SEM) and transmission electron microscopy (TEM) observations. The outer diameter of the tubules can be controlled by the pore size of the template (200–800 nm), whereas the wall thickness is always constant, independent of the Dp value. The (PEI/HSA)3 (PEI: polyethylenimine) nanotubes showed a slightly thin wall of 39±5 nm. CD spectra of the multilayered (PEI/HSA)n film on a flat quartz plate suggested that the secondary structure of HSA between the polycations was almost the same as that in aqueous solution. The three‐cycle LbL depositions of PLA and ferritin (Mw=460 kDa) or myoglobin (Mb, Mw=1.7 kDa) into the porous PC membrane also gave cylindrical hollow structures. The wall thickness of the (PLA/ferritin)3 and (PLA/Mb)3 nanotubes were 55±5 nm and 31±4 nm; it depends on the globular size of the protein (ferritin>HSA>Mb). The individual ferritin molecule was clearly seen in the tubular walls by SEM and TEM measurements.
Why Platinum Catalysts Involving Ligands with Large Bite Angle Are so Efficient in the Allylation of Amines: Design of a Highly Active Catalyst and Comprehensive Experimental and DFT Study

Published: September 2008

AbstractThe platinum‐catalyzed allylation of amines with allyl alcohols was studied experimentally and theoretically. The complexes [Pt(η3‐allyl)(dppe)]OTf (2) and [Pt(η3‐allyl)(DPP‐Xantphos)]PF6 (5) were synthesized and structurally characterized, and their reactivity toward amines was explored. The bicyclic aminopropyl complex [Pt(CH2CH2CH2NHBn‐κ‐C,N)(dppe)]OTf (3) was obtained from the reaction of complex 2 with an excess of benzylamine, and this complex was shown to be a deactivated form of catalyst 2. On the other hand, reaction of complex 5 with benzylamine and allyl alcohol led to formation of the 16‐VE platinum(0) complex [Pt(η2‐C3H5OH)(DPP‐Xantphos)] (7), which was structurally characterized and appears to be a catalytic intermediate. A DFT study showed that the mechanism of the platinum‐catalyzed allylation of amines with allyl alcohols differs from the palladium‐catalyzed process, since it involves an associative ligand‐exchange step involving formation of a tetracoordinate 18‐VE complex. This DFT study also revealed that ligands with large bite angles disfavor the formation of platinum hydride complexes and therefore the formation of a bicyclic aminopropyl complex, which is a thermodynamic sink. Finally, a combination of 5 and a proton source was shown to efficiently catalyze the allylation of a broad variety of amines with allyl alcohols under mild conditions.
Mechanism of the Palladium‐Catalyzed Carbohydroxylation of Allene‐Substituted Conjugated Dienes: Rationalization of the Recently Observed Nucleophilic Attack by Water on a (π‐Allyl)palladium Intermediate
Authors: Karlsson Erik A. , Bäckvall Jan‐E. 
Published: September 2008

AbstractThe mechanism of the palladium‐catalyzed oxidative carbohydroxylation of allene‐substituted 1,3‐cyclohexadiene was studied by DFT calculations. All intermediates and transition states of the reaction were identified and their structures were calculated. The calculations confirm the mechanism previously proposed and show that the CC bond‐forming step occurs via insertion of one of the double bonds of 1,3‐cyclohexadiene into a Pdvinyl bond of a vinylpalladium intermediate. This reaction leads to a (π‐allyl)palladium intermediate, and coordination of benzoquinone and a double bond in the molecule to Pd creates a highly reactive cationic π‐allyl complex, which is readily attacked by water according to the calculations.
Origin of Diastereocontrol in the Oxy‐Michael Reactions of δ‐Lactol Anions: A Computational and Experimental Study
Authors: Richardson Robert D. , Hernandez‐Juan Felix A. , Ward John W. , Dixon Darren J. 
Published: September 2008

AbstractThe diastereoselectivity in the alkylation and Michael addition of “naked” 6‐substituted δ‐lactolates has been studied by density functional (B3LYP) calculations with ab initio (MP2) energy refinements. The resulting proposed model for the origins of stereocontrol in this reaction has been tested by experiment. The reactions lead to a high cis diastereoselectivity across the THP ring due to the preference for both the alkoxide and the 6‐substituent to sit equatorial in the alkylation transition structure. In the oxy‐Michael addition of these lactolates to β‐substituted nitroolefins, we propose that the high diastereoselectivity β‐ to the nitro group is a result of a combination of steric, stereoelectronic and solvation factors.
Sonochemical Synthesis under a Magnetic Field: Fabrication of Nickel and Cobalt Particles and Variation of Their Physical Properties
Authors: Abu‐Much Riam , Gedanken A. 
Published: September 2008

AbstractWe report on the variation of the physical properties of nickel and cobalt nanoparticles prepared by using ultrasound irradiation as energy source. First, we describe a sonochemical method for preparing aggregated particles. Second, we interpret the results on the basis of Einstein's theory (1905), which deals with a mathematical expression for the diffusivity of particles into solvents. This theory explains the stability of organosols of nickel and cobalt nanoparticles in polyethylene glycol. Finally, the effect of applying an external magnetic field during sonochemical formation of both aggregated particles and their stable colloids is investigated.
