Abstract
Phosphine, the phosphorus analog of ammonia, has found importance in research today because of its properties as a reducing agent. It acts as a deoxygenating agent on certain organic compounds and has been used to prepare hypergolic rocket fuels of organic phosphines. Because of its analogy to ammonia, which forms many complexes, phosphine may also be used as a complexing agent, although it does not form complexes as readily as ammonia.
