Reaction of [Ru3(CO)12] with Phenazine: Synthesis of C-Metalated Derivatives That Formally Arise from a C–H Oxidative Addition or a Long-Distance C-to-N Prototropy
摘要:
Three products, [Ru-3(mu-H)(mu(3)-{(C6H4)(C6H3)N-2})(CO)(9)] (1), [Ru-4(mu(4)-{(C6H4)(C6H3)N2H})(mu-CO)(CO)(10)] (2), and [Ru-6(mu(5)-{(C6H4)(C6H3)-N2H})(mu-CO)(3)(CO)(12)] (3), have been prepared by treating [Ru-3(CO)(12)] with phenazine. Compounds 2 and 3 are formed from compound 1 by stepwise addition of Ru(CO)(n) fragments. While compound 1 has a C-metalated ligand that arises from an oxidative addition of a phenazine C-H bond, compounds 2 and 3 contain a C-metalated phenazine NH tautomer. In these complexes, the resulting ligands are attached to three (1), four (2), or five (3) metal atoms using different coordination modes.
