(SPRINGER, 2011)
The presence of paramagnetic species in the aqueous ring opening metathesis polymerizations of the exo,exo-7-oxabicyclo[2.2.1]hept-5-ene-2,3-dicarboxylic acid monomer with RuCl(3) and K(2)[RuCl(5)H(2)O] compounds was studied ...
Cross-link in norbornadiene-based polymers from ring-opening metathesis polymerization with pyrrolidine-based Ru complex
(2018-08-01)
Ring-opening metathesis polymerization (ROMP) of norbornadiene (NBD) with [RuCl2(PPh3)2(pyrrolidine)] as the starting complex was evaluated as a function of reaction time, solvent volume, and atmosphere type at 25 °C. ...
Cooperative Effects of Aniline with DMSO in RuII Complexes: Tuning the Reactivity for Ring-Opening Metathesis Polymerization
(2019-11-10)
The complex cis,fac-[RuCl2(DMSO–O)(DMSO–S)3] [1] reacted with aniline (NH2Ph) under reflux to produce the complex trans,cis,cis-[RuCl2(DMSO–S)2(NH2Ph)2] [2], whereas at room temperature the resulting complex was ...
ROMP como um método versátil para a obtenção de materiais poliméricos diferenciadosRomp as a versatile method for the obtention of differentiated polymeric materials
(Sociedade Brasileira de Química, 2012)
Ring Opening Metathesis Polymerization (ROMP) of cyclic olefins is a powerful transition metal-catalyzed reaction for syntheses of polymers and copolymers. The key feature of this reaction is the [2+2]-cycloaddition ...
