Niobium is not found in nature in its free form, but usually in the form of oxides and usually with the tantalum element. The largest niobium reserves are in Brazil. The use of niobium compounds in organic synthesis has ...

In heterogeneous catalysis, many transition metals and its derivatives, such as titanium and iron, have been vastly studied as nanoscale catalysts, but little is known about the use of niobium compounds. Being biodegradable ...

The growing interest in, and applications of, niobium compounds in organic synthesis and catalysis are surveyed, with a focus on their efficiency and versatility in several classical and broad organic reaction types. It ...
