In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Effects of Initiator Structure on Activation Rate Constants in ATRP, published in 2007-03-20, which mentions a compound: 19481-82-4, mainly applied to copper mediated ATRP initiator structure influence, Synthetic Route of C3H4BrN.
Activation rate constants (kact) for a variety of initiators for Cu-mediated ATRP were determined under the same conditions. The ratio of the activation rate constants for the studied alkyl (pseudo)halides exceeds 1 million times. The activation rate constants increase with initiator substitution (e.g., for primary, secondary, and tertiary α-bromoesters the ratios are ∼110:80), with the radical stabilizing α-substituent (e.g., alkyl bromides with -C(O)NEt2, -Ph, -C(O)OMe, and -CN groups the ratios are ∼1:4:8:600 but with both α-Ph and α-C(O)OEt∼140,000), and with the leaving atom/group (e.g., for Me 2-halopropionates: chloro:bromo:iodo ∼1:20:35, but benzyl bromide is ∼10,000 more reactive than the corresponding isothiocyanate/thiocyanate).
In some applications, this compound(19481-82-4)Synthetic Route of C3H4BrN is unique.If you want to know more details about this compound, you can contact with the author or consult more relevant literature.
