Kinetics of anionic polymerization of β‐myrcene in hydrocarbon solvents

open access: yesPolymer International, EarlyView.
The process of anionic polymerization of β‐myrcene in hydrocarbon solvents was examined by kinetic studies and quantum chemical calculations. Abstract The kinetics of anionic polymerization of β‐myrcene initiated by sec‐butyllithium were examined in saturated and unsaturated hydrocarbon solvents, i.e. cyclohexane, cyclohexene, 4‐vinylcyclohexene and dl‐

trans-Ethylenedi-p-phenylene diacetate

open access: yesActa Crystallographica Section E, 2009
The centrosymmetric title compound, C18H26O4, was prepared in high yield from 4-acetoxystyrene via Ru-catalysed homo-olefin metathesis. Exclusive formation of the E-configurated isomer was observed.

Emerging Agents for Boron Neutron Capture Therapy: Biomolecular Carriers Paving the Way for Precision Radiotherapy

open access: yesPrecision Radiation Oncology, EarlyView.
Boron neutron capture therapy (BNCT) requires key non‐negotiable technical criteria: megadose administration, precise tumor‐specific targeting, favorable biocompatibility, and sustained tumor retention. Overcoming these interconnected challenges fundamentally depends on biomolecular carriers, which are critical for translating the therapeutic potential

Cationic Tungsten(VI) Penta-Methyl Complex: Synthesis, Characterization and its Application in Olefin Metathesis Reaction

open access: yesOil & Gas Science and Technology, 2016
Tungsten-hexa-methyl readily reacts with B(C6F5)3 in dichloromethane and generates the corresponding well-defined cationic tungsten-penta-methyl complex which was identified precisely by 1H NMR, 13C NMR, 1H-13C NMR correlation spectroscopy.

Dimethyl‐, Diethyl‐, and Propylene Carbonates: An Emerging Class of Green Solvents for Organic Synthesis

open access: yesThe Chemical Record, EarlyView.
This review highlights recent advances in the use of organic carbonates, dimethyl carbonate (DMC), diethyl carbonate (DEC), and propylene carbonate (PC), as solvents in organic synthesis. Based on over seventy studies from the past 6 years, it shows their application in different organic reaction types, emphasizing their role in safer and more ...

trans-1,2-Bis(3,5-dimethoxyphenyl)ethene

open access: yesActa Crystallographica Section E, 2009
The title compound, C18H20O4, was prepared in high yield from 3,5-dimethoxystyrene via a Ru-catalysed homo-olefin metathesis. Exclusive formation of the E-configurated isomer was observed. Interestingly, one symmetric unit contains two molecules adopting

Synthesis and Thermolysis of Ylidyl‐Substituted Stannylenes

open access: yesZeitschrift für anorganische und allgemeine Chemie, EarlyView.
The synthesis of an amino(ylidyl)stannylene is reported. The title compound was characterized via X‐ray diffraction and features a Sn2C2 heterocycle. Thermal treatment of the stannylene leads to the elimination of the amine. The products of the thermolysis are discussed.

Modification of poly(lactic acid) via Olefin cross-metathesis [PDF]

open access: yes, 2017
Poly(lactic acid), PLA, is a viable replacement to petroleum derived polymers due to its renewable feedstock, biodegradability and bioassimilability, yet improvements in its physical, thermal and mechanical properties are required before it can fully ...
