Some dimethyl{tris(trimethylsilyl)methyl} silanolato derivatives of tantalum(V), chromium(III) and manganese(II)

Journal Article


Abstract


  • The reaction between tantalum(V) chloride and one equivalent of Me2{(Me3Si)3-C}SiOLi ((trisilox)Li) gave [(trisilox)TaCl4] (2). With two equivalents of (trisilox)Li, the major product was the trisubstituted species [(trisilox)3TaCl2] (3); 3 was the only complex formed in the reactions employing three or five equivalents of (trisilx)Li. The compounds [(trisilox)3Cr] (4) or [(trisilox)2Mn · LiCl] (5) were obtained by treatment of chromium(III) chloride or manganese(II) chloride with two equivalents of (trisilox)Li, respectively. Preliminary crystallographic results for 4 show a trigonal-planar arrangement of the ligands about the chromium atom. © 1988.
