Abstract

Polycarbosilane containing Cu(II) (Cu-PCS) was prepared. The performance of Cu-PCS as a catalyst was verified using the three-component Biginelli reaction. It was found to be a good catalyst. The product, dihydropyrimidinone, could be easily isolated from the reaction medium. The heterogeneous nature of the catalyst helped in separating the product. The reaction conditions were optimized, and the catalyst was found to be reusable. The catalytic activity of Cu-PCS was compared with that of Cu ion supported on SBA-15 and amorphous silica. Cu-PCS exhibited better catalytic activity, recyclability and was devoid of metal leaching.
