Category: ruthenium-catalysts. So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic. Compound: 2-Bromopropanenitrile, is researched, Molecular C3H4BrN, CAS is 19481-82-4, about Cu complexes with phosphorous ligands for living radical polymerization of MMA.
Cu/phosphorous ligand complexes were prepared and applied to atom transfer radical polymn (ATRP). MMA polymerization with CuBr/phosphonidine phosphine exhibited high conversion (∼80%) in 5 h along with linear increase of ln([M]0/[M]) vs. time, indicating constant concentration of the propagating radicals. Mol. weight increased with conversion, suggesting living polymerization characteristic of the system. However, large difference between measured and theor. mol. weight and broad mol. weight distribution suggest insufficient control over the polymerization, probably due to low deactivation rate constant of the system for MMA polymerization Polymerizations performed at different ligand to CuBr ratios, different monomer to initiator ratios and with different initiator, different ligands did not afford better control over the polymerization, suggesting inherently limited controllability of CuBr/phosphorous ligand system for MMA polymerization
