Abstract
|
|
|
|
New Palladium(0)-olefin complexes, (PMe3)2Pd{CH2=C(CH3)COOH} and (PMe3)2Pd{(CH3)CH=CHCOOH} have been prepared by treating Pd(PMe3)2(styrene) with methacrylic acid and trans-crotonic acid, respectively. These complexes were characterized by elemental analysis, IR and 1H-, 13C-, and 31P-NMR spectroscopy. The carboxylic acid entity was found non-bonded with palladium while π-bond is formed between the olefin double bond and Pd(0). The results are compared with the metallacycle formation the reaction of Pd(PMe3)2(styrene) with 3-butenoic acid.
