    • A pentacoordinated intermediate has been proposed to explain the β-H elimination in [PdEt2(PR3)2] to give ethane and ethene, where the addition of phosphine has little effect on the reaction rate:

    • Other less-common mechanisms have been reported for β-H elimination in palladium allyls, such as direct deprotonation of a β-H in the presence of a base (see for example:

The synthesis of dienes from allylic acetates catalyzed by palladium has been carried out in the presence of monodentate phosphines, where cationic complexes and neutral allyls (with coordinated acetate) can be present in solution (see ref. 2f). Our results suggest that H-elimination in this reaction occurs on the neutral allylic complexes
