Early–late heterobimetallic Rh–Ti and Rh–Zr complexes via addition of early metal chlorides to mono- and divalent rhodium†
Abstract
Addition of TiCl4 or CHtBu) (1) rapidly gives complexes (PNP)Rh(MCl3)(Cl) (M = Ti, 2; Zr, 3) in 75–77% yield (PNP = (4-Me-2-(iPr2P)–C6H3)2N). Compound 2 can also be synthesized via a reaction of (PNP)RhCl with TiCl3 or of (PNP)TiCl3 with 1/2 [(cod)RhCl]2.
