This review has been centralized on applications of phthalic anhydride (PA) as a valuable and significant heterocyclic substrate in two- and multicomponent organic reactions.
This work achieved the arylation of gold nanoclusters with maintained templates, bridging two major research areas of gold chemistry—arylgold complexes and gold nanoclusters.
Photosensitizer-free visible light-mediated cross-coupling of aryldiazonium tetrafluoroborates and alkynyltrimethylsilanes has been achieved using a recyclable SBA-15-anchored triphenylphosphine–gold(I) complex as a catalyst.
Sb(III)–Gum Arabic composite as a unique natural-based and nontoxic catalyst was synthesized and characterized by FT-IR, XRD, TGA, ICP, BET, EDX and mapping.
The tremendous potential of transition metal-free multi-component reactions (MCR) in the synthesis of N-heterocyclic frameworks is examined in this review, offering a complete overview of this subject matter.
