ESR Studies of Chemically Dehydrofluorinated Poly(vinylidene fluoride)
Magnetic Resonance in Solids. Electronic Journal, 2008 X-band ESR of chemically dehydrofluorinated poly(vinylidene fluoride) films has been studied in the 150 ÷ 375 K temperature range. Dehydrofluorinated films reveal an ESR signal with g-factor close to that of the free electron. The ESR parameters (integral intensity, width, g-factor) of the samples depend on duration of the chemical reaction, storage ...

New Synthesis of 3-Fluoropyrroles
, 2016 5-Alkoxymethyl-2-aryl-3-fluoro-1H-pyrroles and 2-aryl-3-fluoro-1H-pyrrole-5-carbaldehydes were efficiently prepared from the corresponding 2-aryl-5-(bromomethyl)-1-pyrrolines via electrophilic α,α-difluorination of the imino bond, using Selectfluor (1 ...
