Abstract
An important challenge in the artificial fixation of N2 is to find atom efficient transformations that yield value-added products. Here we explore the coordination complex mediated conversion of ubiquitous
species, CO and N2, into isocyanate. We have conceptually split the process into three steps: (1) the sixelectron splitting of dinitrogen into terminal metal nitrido ligands, (2) the reduction of the complex by two
electrons with CO to form an isocyanate linkage, and (3) the one electron reduction of the metal isocyanate complex to regenerate the starting metal complex and release the product. These steps are
explored separately in an attempt to understand the limitations of each step and what is required of a
coordination complex in order to facilitate a catalytic cycle. The possibility of this cyanate cycle was
explored with both Mo and V complexes which have previously been shown to perform select steps in
the sequence. Experimental results demonstrate the feasibility of some of
