Recently, the direct incorporation of heteroatom into imidazole-fused heterocycles through
transition metal-free CH functionalization has rapidly been advanced and become an eco …

We report herein an effective method for the halogenation of imidazo-fused heterocycles
using readily available sodium salts (NaCl/NaBr/NaI) as halogen source and K2S2O8 (or) …

A metal-free, environmentally friendly protocol for the arylselenylation of 2 H-indazole has
been developed using a catalytic amount of I2 under ambient conditions. A number of 3 …

A sustainable and transition metal-free approach for C3 chalcogenation and
chalcogenocyanation of imidazopyridines with KXCN (X= S or Se) has been developed …

Alkylated imidazopyridines are crucial structures for medicinal chemistry. Here, an efficient
method for the C3–H alkylation of imidazopyridines was devised. Under Lewis acid …

A metal-free and base-free procedure for the phosphorylation of imidazo [1, 2-a] pyridines
with phosphine oxides under the irradiation of visible light at room temperature in green …

A copper (I)-catalyzed sulfur-bridged dimerization of imidazopyridines has been developed
using isothiocyanate as the sulfur source. This method enables a switchable synthesis of bis …

A series of organic sulfonate inner salts, viz., aprotic imidazolium-and pyridinium-based
zwitterions bearing sulfonate groups (− SO3–), were synthesized for the catalytic conversion …

The novel acidic ionic liquid [BEMIM][HSO 4] was prepared and characterized by FT-IR, 1 H
NMR, 13 C NMR, DEPT-135, LC-Mass, and elemental analysis techniques. It was examined …

An electrochemical oxidative iodination of imidazo [1, 2-a] pyridines is achieved in this study.
This reaction utilizes NaI as an iodine source and a supporting electrolyte under metal-free …
