Cyclopentadienyl allyl palladium


Cyclopentadienyl allyl palladium is an organopalladium compound with formula Pd. This reddish solid is volatile with an unpleasant odor. It is soluble in common organic solvents. The molecule consists of a Pd centre sandwiched between a Cp and allyl ligands.

Preparation

This complex is produced by the reaction of allylpalladium chloride dimer with sodium cyclopentadienide:

Structure and reactions

The 18-electron complex adopts a half-sandwich structure with Cs symmetry, i.e., the molecule has a plane of symmetry. The complex can be decomposed readily by reductive elimination.
The compound readily reacts with alkyl isocyanides to produce clusters with the approximate formula n. It reacts with bulky alkyl phosphines to produce two-coordinated palladium complexes:
The compound has been used to deposit thin film chemical vapor deposition of metallic palladium.
