The present invention embodies some novel carbamate compounds, viz.4-methylpiperazinel- carbmic Acid (4-MPipzcbmH) and its complexes with copper(II) and zinc(I1) metal ions: [Cu (4-MPipzcbmH)2]X2: (X= Cl,ClO4,NO3) and [Zn(4-MpipzcbmH)2]Cl2. The compounds have been synthesized using green synthetic routes and exhibit potential insecticidal activity against various potato pests with low residues.
