Abstract
|
The 4-(benzyloxy)benzyl chloride polymer-bound (BBC-Polym) was functionalized with Bismarck Brown Y (BBY: 4,4′-(1E,1E′)-1,3-phenylenebis(diazene-2,1-diyl)dibenzene-1,3-diamine (BBC-Polym@BBY), the corresponding novel nanoparticle Pd catalyst prepared by addition of PdCl2 (BBC-Polym@BBY@Pd), and the catalyst used as an efficient heterogeneous catalyst for the synthesis of a range of N-arylsulfonyl cyanamides from the reaction of arylcyanamides with arylsulfonyl chloride at r.t. in EtOH. Recyclability of the catalyst, high yield, short reaction times, and easy work up are the attracting features of this protocol.
