A photochemical route to a square planar, ruthenium(iv)-bis(imide).

The square planar, ruthenium(iv) bis(imide) trans-Ru(NAr)2(PMe3)2 can be prepared photochemically from a Ru(ii) tetrazene. Additionally, we report reactivity of the Ru(iv) bis(imide) species, similar to that of the osmium derivative. Attempts to change both imide group and phosphine substituents are presented, which led to alternative reactivity.
