A dinuclear Cu(OAc)2-anchored SBA-15 silica was synthesized, confirmed and showed excellent catalytic activity for the azide–alkyne cycloaddition reaction in water.
The pseudo-four component click synthesis of dibenzylated 1,2,3-triazoles derived from aniline is reported. The cycloaddition of sodium azide to N-(prop-2-ynyl)-benzenamine (I) in the presence of equimolar amounts of p-substituted benzyl derivatives, yields a mixture of mono- and dibenzylated 1,2,3-triazoles. When two equivalents of the benzyl derivative are added to the multicomponent reaction, the
