Palladium complexes with Pd -> B dative bonds: Analysis of the bonding in the palladaboratrane compound [kappa(4)-B(mim(But))(3)]Pd(PMe3)

摘要

The dinuclear complex {[mu-kappa(1), kappa(3)-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); treatmentof {[mu-kappa(1), kappa(3)-B(mim(But))(3)]Pd}(2) with PMe3 affords the mononuclear boratrane derivative [kappa(4)-B(mim(But))(3)]Pd(PMe3), for which a molecular orbital analysis indicates that the palladium center possesses a d(8) configuration.
