The formation, reactivity and interconversion of novel η1- and η3-triazacyclononane complexes of rhodium(i) and rhodium(iii)

Abstract

We have successfully synthesised and characterised a number of η¹- and η³-triazacyclononane Rh^I and Rh^III derivatives. By using different reaction conditions, we have been able to convert one of the η¹-triazacyclononane complexes to an η³-derivative. Also, we have observed a rare example of an addition of an organic fragment to a metal bound ligand to form a quaternary carbon centre.
