Reactivity of a Four-Membered Vanadacycle Ring Supported by Bulky Silazanate. Regioselective Hydrogenation of Pyridine
摘要:
The dinuclear {[(Me3Si)2N]V[mu-N(SiMe3)-Si(Me2CH2]}2 complex, containing a four-membered metallacyclic ring, has been obtained via reaction of VCl3(THF)3 with (Me3Si)2NLi. The reactivity of the metallacycle has been investigated with respect to the coordination of bases, hydrogenation, and insertion of alkynes.
