Abstract

Abstract: The complex [(nacnac)Ti(OAr)]2 (μ2 :η 2, η 2 ‐P2 ) (1 ) is formed via reductive decarbonylation of the phosphaethynolate ion − [OCP], which serves as a P atom source. Complex1 is the first structurally characterized Group 4 transition metal P2 complex and its structure reveals the rhombic Ti2 P2 core is essentially planar with short bond lengths suggesting some degree of multiple bonding character between the Ti–P and P–P sites. Computational studies of1 provide an understanding of the Ti2 P2 core as well as the origin of the highly downfield 31 P NMR spectroscopic signal.
