An efficient, simple and green procedure has been developed for the synthesis of tetrahydrobenzo[b]pyran deravitives via the condensation one-pot and three-component of aldehydes, malononitrile and 5,5-dimethyl-1,3-cyclohexandione or 1,3-cyclohexandione in present heterogeneous catalysts silica-supported antimony(III)chloride (SbCl3/SiO2) and nano catalyst CdO under condition reflux in Ethanol. The advantages this method can be presented to the use of catalysts cheap, accessible, simple separation products, improve the efficiency of products, the use of solvents that are relatively less environmental pollution, an easy way to recyclability and reused catalyst. Also, in present work, (2A-3C-4P-5O-TBP) was used as a platform for dispersion and immobilization of AgNPs on the glassy carbon electrode. The functional groups at (2A-3C-4P-5O-TBP) have effective interaction with silver ions and cause to electrochemical immobilization of AgNPs on the electrode surface. The surface of electrode was investigated by scanning electron microscopy (SEM) and the results showed good distribution of AgNPs on the electrode surface modified with (2A-3C-4P-5O-TBP).
