Synthesis and Characterization of Fused-Ring Iridapyrroles

Organometallics. 2008 Oct 15;27(22):2744-5747. doi: 10.1021/om8008712.

Abstract

Treatment of aromatic nitriles with methyllithium produces N-lithiated imine reagents which, when reacted with (η(2)-cyclooctene)(Cl)Ir(PMe(3))(3), generate fused iridaazacycles via ortho-metallation. Mono-protonation of these iridaazacycles produces fused iridapyrrole derivatives, while di-protonation leads to several different pathways.
