Cu2+-crosslinked CM-cellulose/diatomite composite beads (CuII@CMC/DE) were prepared in simple and efficient way using ionic crosslinking techniques. In CuII@CMC/DE beads, diatomite serves as a reinforcing filler, and divalent copper cation acts as crosslinking agent. The chem. structure and morphol. of as-fabricated CuII@CMC/DE beads were well characterized using various techniques such as ICP, FT-IR, XRD, SEM, EDS, elemental mapping, TEM, XPS, and TGA. The CuII@CMC/DE beads exerted superior catalytic performance in CuAAC reactions of benzyl halides, sodium azide, and alkynes to yield regioselective 1,4-disubstituted-1,2,3-triazoles in excellent yields under green conditions. In these resultant catalytic composite beads, Cu2+ was used not only as a crosslinking agent but also as a metal catalyst for CuAAC reaction. The composite beads can be easily separated by filter and reused at least four times without any significant decrease on its activity and selectivity.
