Triazole Appended Phosphines: Synthesis, Palladium Complexes, and Catalytic Studies

Abstract

The copper(I)‐catalyzed triazole formation from azides and terminal alkynes has received the benchmark of “click chemistry” because of its dependability and explicitness. The extensive utility of click chemistry in all aspects from making classical phosphine ligands, investigating its reactivity in serving as an effective catalyst for various organic transformations is well documented. Therefore, designing a decent ligand system with adequate nature and vast diversity is vital for having to deal with the demanding substrates in this area. Due to the benefits of broad functional group tolerance and the use of stable reagents, the Pd‐catalyzed organic transformations are most valuable in fine chemical synthesis and drug industry. The present review focuses mainly on the synthesis of a novel class of triazole based phosphines and their complexation behavior with palladium and catalytic applications.
