e with zerovalentnickelcomplexes, prepared from bis(acetylacetonate)nickel(II), with either pyridine or triphenylphosphine as ligands, and triethylaluminium as reducing agent has been carried out. The α-methylene protons show a diastereotopic effect which could be explained by a rigid bridged hydrogen bound through the oxygen atom of the acetanilide group to one of the α-methylene protons and partially

mononitration of indolines either at -C5 or -C7 positions is reported here. The role of multiple weak interactions such as steric factors, electronic effects, cation-π interaction, solvent polarity, etc. was established for the 100% regioselective electrophilicaromatic (ArSE) nitration using Cu(NO3)2 or AgNO3.
