Coordination compounds of π-allyl palladium (ii) with substituted olefins

The coordination compound of palladium and platinum metal are use in homogenous catalysis and developed many organometallic compound which are mainly use in the arrylation of olefins and coupling reaction between substituted aromatic compound with olefins. Some researchers note that arylation was found the on a π-carbon atom of styrene and reported novel method of synthesizing stilbene derivatives by substitution of aromatic compounds for hydrogen on the double bond of the styrene-palladium chloride complex. Palladium (II) chloride can also catalyze the arylation reaction in the presence of metal acetates such as those of sodium or potassium, although palladium (II) chloride compounds have no function as an arylation catalyst without metal acetate.
