phosphoranyl radical chemistry allows for precise cleavage of a stronger C-O bond and formation of a weaker C-Cbond by 1,5-aryl migration under mild reaction conditions. This new protocol is independent of substrate redox-potential, electronic, and substituent effects. It affords a general and promising access to 60 examples of synthetically versatile o-amino and o-hydroxy diaryl ketones under redox-neutral
Tractable doped electroactive polymers, comprising recurring units of a fused nitrogen-containing unsaturated heterocyclic ring system, are fabricated from the virgin polymer by contacting the polymer with donor or acceptor conductivity modifier atoms or groups of atoms.
The present invention is to provide a resin composition excellent in moisture absorption property, heat resistance, adhesive property and electric characteristics, and excellent in molding property, and suitable for an insulating material such as a multilayer wiring substrate, electronic parts, etc., and an adhesive film.
There is disclosed a resin composition comprising (A) a polymer containing a quinoline ring represented by the formula (1) in the structure such as 6,6′-bis(2-(4-fluorophenyl)-4-phenylquinoline) and 4,4′-(1,1,1,3,3,3-hexafluoro-2,2-propylidene)bisphenol, etc., and (B) a bismaleimide compound represented by the formula (2) such as 2,2-bis((4-male-imidophenoxy)phenyl)propane, etc.
