Synthetic applications of cationic iron and cobalt carbonyl complexes.
Metal carbonyl stabilized cationic species react with a wide range of nucleophiles under mild conditions, and have thus found many synthetic applications. In this Perspective, we describe the utility of iron carbonyl dienyl cations in solution and solid phase parallel synthesis, and in the development of a new synthetic route towards oseltamivir phosphate (Tamiflu). We also discuss the solid phase version of the Nicholas reaction, employing cobalt carbonyl stabilized propargylic cations, and giving access to substituted alkynes.
