“…The sheer number of other recent examples of H 2 Me 4 bpz-based metal–organic frameworks emphasizes the utility of this bipyrazole ligand. These frameworks combine H 2 Me 4 bpz with various transition metals, including manganese [ 68 ], iron [ 69 ], cobalt [ 68 , 70 , 71 ], nickel [ 68 ], copper [ 72 ] zinc [ 73 ], silver [ 74 , 75 , 76 ] and cadmium [ 68 , 77 , 78 ], yielding a diverse array of framework topologies and functionalities. These frameworks were investigated for applications ranging from antibacterial therapy [ 76 ] to the photocatalytic degradation of organic pollutants [ 71 ], and chemists are sure to push the boundaries of H 2 Me 4 bpz-based metal–organic frameworks further in the coming years.…”

Pyrazole, a member of the structural class of azoles, exhibits molecular properties of interest in pharmaceuticals and materials chemistry, owing to the two adjacent nitrogen atoms in the five-membered ring system. The weakly basic nitrogen atoms of deprotonated pyrazoles have been applied in coordination chemistry, particularly to access coordination polymers and metal-organic frameworks, and homocoupling reactions can in principle provide facile access to bipyrazole ligands. In this context, we summarize recent advances in homocoupling reactions of pyrazoles and other types of azoles (imidazoles, triazoles and tetrazoles) to highlight the utility of homocoupling reactions in synthesizing symmetric bi-heteroaryl systems compared with traditional synthesis. Metal-free reactions and transition-metal catalyzed homocoupling reactions are discussed with reaction mechanisms in detail.
