They can behave as catalysts or precats - a pretty rare use of isocyanides as spectator ligands in catalysis. We stand on the shoulders of giants - Otsuka, Kubiak, Muetterties, and others who worked on this chemistry in the 70s and 80s. And don’t worry, the complexes are not smelly. :-)

Thanks for this initiative, Craig! I would like to be added as well!
