✦ Synopsis

Abstract

We show that both palladium(0) and palladium(II) metal centers are capable of coordinating two monodentate MOP (=(R)‐2‐(diarylphosphino)‐1,1′‐binaphthalene) ligands in a pseudo‐cis orientation, despite published statements to the contrary. In addition to [Pd(η^3^‐C~3~H~5~)(MeOMOP)~2~]BF~4~ (MeOMOP=(R)‐2‐(diphenylphosphino)‐2′‐methoxy‐1,1′‐binaphthalene), the first examples of chiral bis κC^1^‐prop‐2‐enyl (η^1^‐CH~2~CHCH~2~) complexes [cis‐Pd(κC^1^‐C~3~H~5~)~2~(MeOMOP or MOP)~2~], are shown to be relatively stable. Further, coordinated MOP and MeOMOP both show stronger propensity towards novel intramolecular π‐olefin complexation than the CNMOP analogue. The solid‐state structure of [Pd(fumaronitrile)(MOP)~2~] is reported.
