Ligand displacement reactions of PtR2(cod) with water soluble tertiary phosphines such as 1,2-bisdi(hydroxymethyl)-phosphino}ethane (DHMPE) or tris(hydroxymethyl)phosphine (THMP) gave new water-soluble diorganoplatinum(II) complexes PtR2L2 [L2=(HOCH2)2PCH2CH2P(CH2OH)2: R=Me (1a); Et (1b); Ph (1c), L=P(CH2OH)3: R=Me (2a); Et (2b); Ph (2c)] at room temperature. They were considerably stable in water and the thermolyses of 1b and 2b at 80 °C liberate ethylene and ethane via β-hydrogen elimination and hydrolysis.
