Highly reduced organometallics 42. A new method for the syntheses of [V(CO)6]− and [V(PF3)6]− involving anthracenide mediated reductions of VCl3(THF)3
摘要:
A new mild (0 degrees C, 1 atm P) and high yield (70%) synthesis of [V(CO)(6)](-) by the sodium anthracenide mediated reductive carbonylation of VCl3(THF)(3) is presented. This same procedure is also shown to provide the first conventional, non-photolytic route to [V(PF3)(6)](-), a remarkably stable substance. Corresponding sodium naphthalenide reductions provide much lower yields of these vanadates. (C) 1998 Elsevier Science S.A.
