For the first time, a new and facile Ag@PM-b-B nanocomposite electrochemical sensor was successfully developed for the detection of glucose. Also, the magnetically recoverable catalyst was easily recycled at least ten times without significant loss of catalytic activity.
A simple and convenient approach to the synthesis of symmetrical N,N′-alkylidine bisamides is described. Aromatic and aliphatic nitriles react with aromatic aldehydes in the presence of sulfamic acid to give the corresponding bisamides in moderate yields.Key words: alkylidine bisamides, nitrile, sulfamic acid.
