Palladium complexes with Pd→B dative bonds: Analysis of the bonding in the palladaboratrane compound [κ4-B(mimBut)3]Pd(PMe3)

Abstract

The dinuclear complex {[μ-κ¹,κ³-B(mim^But)₃]Pd}₂, which features a Pd→B dative bond, may be obtained by the reaction of [Tm^But]K with Pd(OAc)₂; treatment of {[μ-κ¹,κ³-B(mim^But)₃]Pd}₂ with PMe₃ affords the mononuclear boratrane derivative [κ⁴-B(mim^But)₃]Pd(PMe₃), for which a molecular orbital analysis indicates that the palladium center possesses a d⁸ configuration.
