Abstract : Reactions of PtCl4(2-) with RI (R = CH3, CH2CH20H) in water yield PtCl5R(2-) which were isolated as their NMe4 salts. They decompose in aqueous chloride solution to give ROH and RCL. erythro- and threo-PtCl5(CHDCHDOH)(2-) are obtained by oxidation of PtCl3(cis- and trans CHD=CHD)(-) respectively. Kinetic rate laws and stereochemistry support SN2 displacement by Cl- or H20 as the mechanism of the decomposition reactions.
