Abstract Thermolysis of thiirane oxide leads to production highly reactive sulfur monoxide. The liberated SO can in turn be trapped with a diene scavenger forming dihydrothiophene oxide. Since the intermediate diatomic possesses triplet ground state, transfer proceed on two spin‐state surfaces. Here, we study competition between singlet concerted and stepwise diradical mechanisms utilizing M06‐...

Monodisperse iron oxide nanocrystals were synthesized by a simplified method using iron chloride as precursor. In the presence of Cl ions, the as-produced iron oxide nanocrystals preferred a cubic shape with {100} facets exposed. The function of halogens including Cl and Br ions on stabilizing {100} facets of spinel structured iron oxides, rather than the regulation of thermolysis kinetics and ...

Mild thermolysis of Lewis base stabilized phosphinoborane monomers R(1)R(2)P-BH2⋅NMe3 (R(1),R(2)=H, Ph, or tBu/H) at room temperature to 100 °C provides a convenient new route to oligo- and polyphosphinoboranes [R(1)R(2)P-BH2]n. The polymerization appears to proceed via the addition/head-to-tail polymerization of short-lived free phosphinoborane monomers, R(1)R(2)P-BH2. This method offers acces...

Functionalized polymer nanoparticles react and store molecular oxygen for several weeks in the form of endoperoxides. On-demand controlled release of singlet oxygen by the particles is achieved by thermolysis.

Monodispersed Ag2Se nanocubes and faceted nanocrystals have been synthesized by hexadecylamine (HDA) induced thermolysis of [(PPh3)3Ag2(SeC{O}Ph)2] in a mixture of TOP (tri-n-octyl phosphine) and HDA in the temperature range 95-180 degrees C.

[figure: see text] Thermolysis of lactone 18 initiated a stereospecific transannular nitrone-olefin [3 + 2] cycloaddition to yield tetracycle 19. Methanolysis followed by reductive cleavage of the isoxazolidine yielded 20, representing the azaspirocyclic core of pinnaic acid (1).

Highly crystalline NiO nanoparticles synthesized through a facile thermolysis route were used as photocathode materials in p-type dye-sensitized solar cells resulting in open-circuit voltages exceeding 300 mV with an iodide/triiodide mediator.

AIM The aim of this study was to investigate in vitro the utility of biologically compatible, nontoxic and cell-specific targetable hydrogel nanoparticles (NPs), which have Coomassie® Brilliant Blue G dye (Sigma-Aldrich, MO, USA) covalently linked into their polyacrylamide matrix, as candidates for photothermal therapy (PTT) of cancer cells. MATERIALS & METHODS Hydrogel NPs with Coomassie Bri...

Square planar dialkyl complexes of nickel, palladium and platinum exhibit intriguing difference in their reactivities. Thermolysis pathways of these dialkyls vary depending on the metal, ligands, alkyl groups, geometry as well as the presence or absence of added ligand. Kinetic studies on the thermolysis and trans-cis isomerizations of PdR,L2 (L = tertiary phosphine) complexes showed involvemen...

Five-coordinate platinum(IV) alkyl complexes bearing sterically non-demanding pyridylpyrrolide ligands, (LX)PtMe(3) [LX = 3,5-di-tert-butyl-2-(2-pyridyl)pyrrolide (3a) and 3,5-diphenyl-2-(2-pyridyl)pyrrolide (3b)] have been prepared. An X-ray structure of 3a establishes that it is a five-coordinate Pt(IV) complex with a square-pyramidal geometry. Thermolysis of 3a or 3b in C(6)D(6) with ethylen...
