The preparation and properties of (Ph 3P) 2(CO)(Cl)(H)IrX (X = FPF 5, ClAlCl 3) are reported. The PF 6 complex reacts with water to give the difluorophosphato compound (Ph 3P) 2(CO)(Cl)(H)IrOPOF 2 which was characterized by X-ray structure analysis. The X-ray structure ...
Our two industrially funded projects in this area are focused on the development of new generation soluble Ziegler-Natta type catalysts.Electrophilic Boranes in Organic Synthesis: Extremely Lewis acidic boranes containing C6F5 groups are being employed stoichiometrically and catalytically in hydroboration, h...
The single crystal structure of [Ir(ppy)2(3)]Cl·2H2O·MeCN is also reported. In each complex, the 2,2′:6′,2″-terpyridine (tpy) ligand binds to the metal centre in a bidentate fashion with the non-coordinated pyridine ring folded into the coordination sphere and engaging in a ...
The mechanisms by which Lewis acids coordinate and hence promote reactions such as the Diels-Alder reaction, with a view to using this knowledge to improve the efficiency of catalytic (asymmetric) processes.Physical organic chemistry, mechanisms of Lewis acid catalysed reactions, Diels-Alder reactions,...
The nature of the product from the reaction of 1 and NH 4F in the presence of a halide ion trap has been established.doi:10.1016/0022-328X(90)85195-5Fiona M. Conroy-LewisStephen J. SimpsonElsevier B.V.Journal of Organometallic Chemistry...
This is not so obvious in ordinary macroscopic objects that consist of atoms bonded in a three-dimensional (3D) structure. However, the effect of dimensionality is more than conspicuous in crystalline solids that are arranged in 0D, 1D, or 2D structure. In fact, we observe dramatically ...
