Abstract
The reactivity of cationic Pt-II-phenyl complexes of the type [PtPh(CH2=CHR)(phen)](+) (R = H or Me) has been investigated. In all cases, insertion of the alkene into the Pt-Ph bond has been observed. The fate of the resulting Pt-CH2CHRPh (R = H or Me) derivative depends on the experimental conditions. In the presence of donor ligands (e.g. excess olefin, pyridine or triphenylphosphine) the product is stable, while in the absence of them a rapid rearrangement to form Pt-C6H4(CHRMe)-2 occurs.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
