Due to the difference of electronegativity between bromine (2.96) and carbon (2.55), the carbon atom in a C–Br bond is electron-deficient and thus electrophilic. The reactivity of organobromine compounds resembles but is intermediate between the reactivity of organochlorine and organoiodine compounds...
Lewis acids can efficiently promote free radical atom transfer reactions of an oxazolidinone imide substrate, 1, derived from α-bromo acetic acid. Thus, 1 undergoes a radical chain addition to 1-hexene giving the atom transfer addition compound, 6, in the presence of scandium or ytterbium trifla...
Discusses the use of Lewis acids to promote the atom transfer addition of N-alpha-bromoacetyl-oxazolidinone to 1-hexene. Carbon-bromine bond dissociation energies for Lewis acid complexes of oxazolidinone imide; Role of scandium or ytterbium triflate in promoting the reaction; Competition reaction ...
nitrogen bonding to uncoordinated Pb2+or Iodine antistites48,57. The functionality of the PZDI molecule is superior due to higher electron density in the vicinity of the N-atom compared to PEDAI with an aryl core. Furthermore, we conducted a cross-sectional transmission electron microscopy (TEM...
