Versatility of cycloaddition of electrophilic alkynes to η2-CS2 metal complexes. Reversible isomerisation of 1,3-dithiol-2-ylideneiron and heterometallocyclic complexes
Abstract
The 1,3-dithiol-2-ylideneiron(0) complexes (3) isomerise to heterometallocycles (4), the equilibrium constant and rate constant increasing with donor strengths of the ligands on iron.
