标题:The Presence Of Water In The Common Cecl3/rli Alkylation System
摘要:Dehydration Of Cecl3(H2O)(7) Following Standard Procedures For Making The Commonly-Used Cecl3/rli Reagent Forms A Material Containing Water And Not Anhydrous Cecl3. Heating Cecl3(H2O)(7) At 150 Degrees C And 0.03 Torr For 12 H Forms A Material Which Has An Elemental Composition Of [cecl3(H2O)](N),Contains Water By Karl Fischer Analysis,Reacts With Meli To Form Methane,And Crystallizes From Thf As [ce(Mu-Cl)(3)(Thf)(H2O)](N),In Space Group With A = 6.691(2) Angstrom,B = 7.433(2) Angstrom,C = 10.092(2) Angstrom,Alpha = 84.46(2)Degrees,Beta = 76.72(2)Degrees,Gamma = 74.76(3)Degrees,V = 471.0(2) Angstrom(3),Rho(Calcd) = 2.37 G/cm(3),And Z = 2 At T = 158 K. [ce(Mu-Cl)(3)(Thf)(H2O)](N) Crystallizes In A Layered Structure In Which Eight-Coordinate Cerium Atoms Are Ligated To Terminal Water And Thf Ligands And Six Bridging Chlorides In A Distorted Square Antiprismatic Geometry. The Thf Ligands Extend Above And Below The Layers Which Contain The Water Molecules. Reactions Of ''Cecl3/rli'' Must Take Into Account The Presence Of 1 Equiv Of Water.
