  Synthesis, characterization and reactivity of tetramethylphospholyl complexes of scandium

  摘要：

  Reaction of 2 equiv. of (C4Me4P)Li(tmeda) (tmeda = tetraethylenediamine) with I equiv. Of ScCl3(THF)(3) gave the new compound (eta(5)-C4Me4P)(2)ScCl2Li(tmeda) (1), which was characterized by X-ray crystallography. A phospholyl moiety in I is labile, as demonstrated by reactions of I with LiCH(SiMe3)(2) and Cp*Li (Cp* = C5Me5) to afford, respectively, (eta(5)-Me4C4P)Sc[CH(SiMe3)(2)]Cl2Li(tmeda) (4) and (eta(5)-Me4C4P)Cp*ScCl2Li(tmeda) (5). Attempts to generate alkyl derivatives of the general type (eta(5)-C4Me4P)(2)ScR (R = alkyl) were unsuccessful. (c) 2006 Elsevier B.V. All rights reserved.
