Name: 2-Bromopropanenitrile. Aromatic heterocyclic compounds can also be classified according to the number of heteroatoms contained in the heterocycle: single heteroatom, two heteroatoms, three heteroatoms and four heteroatoms. Compound: 2-Bromopropanenitrile, is researched, Molecular C3H4BrN, CAS is 19481-82-4, about Temperature Effect on Activation Rate Constants in ATRP: New Mechanistic Insights into the Activation Process. Author is Seeliger, Florian; Matyjaszewski, Krzysztof.
Activation rate constants (kact) for a variety of initiators for Cu-mediated ATRP were measured with Cu(I)Br(PMDETA) at various temperatures (i.e., -40 to +60 °C). Reactions of less active alkyl halides were more accelerated by increased temperatures than reactions of more active initiators. Straight Eyring and Arrhenius plots were obtained, from which the activation parameters (i.e., ΔH⧧, ΔS⧧, Ea, and ln A) were determined The activation enthalpies ΔH⧧ are in between 26.0 and 38.7 kJ mol-1 with highly neg. activation entropies (ΔS⧧ = -156 to -131 J mol-1 K-1), which indicate greatly ordered structures of the transition states for these reactions.
