<I>cis-</I> and <I>trans-</I>[PtCl<SUB>2</SUB>(Et<SUB>2</SUB>S)<SUB>2</SUB>] as well as [PtCl<SUB>2</SUB>(EtSCH<SUB>2</SUB>CH<SUB>2</SUB>SEt)] reacted with thallium(I) β-diketonates, Tl(β-dik), to give complexes containing a central-carbon-bonded β-dik ligand. The reaction of <I>cis-</I>[PtCl<SUB>2</SUB>(PEt<SUB>3</SUB>)<SUB>2</SUB>] with Tl(acac) (acac=acetylacetonato) did not give an acetylacetonato complex, but resulted in [Pt(CO<SUB>3</SUB>)(PEt<SUB>3</SUB>)<SUB>2</SUB>], while <I>trans-</I>[PtCl<SUB>2</SUB>(PEt<SUB>3</SUB>)<SUB>2</SUB>] yielded [PtCl(acac)(PEt<SUB>3</SUB>)]. [Pt(PPh<SUB>3</SUB>)<SUB>2</SUB>(H<SUB>2</SUB>O)<SUB>2</SUB>](ClO<SUB>4</SUB>)<SUB>2</SUB> derived from <I>cis-</I>[PtCl<SUB>2</SUB>(PPh<SUB>3</SUB>)<SUB>2</SUB>] reacted with K(acac) and K(tfac) (tfac=trifluoroacetylacetonato) to afford [Pt(acac)(PPh<SUB>3</SUB>)<SUB>2</SUB>]ClO<SUB>4</SUB> and [Pt(tfac)(PPh<SUB>3</SUB>)<SUB>2</SUB>]ClO<SUB>4</SUB>, respectively. Bases such as Et<SUB>3</SUB>N, K(acac), and K(tfac) removed a proton from the latter complex to give [Pt(tfac(2–)-<I>C</I>,<I>O</I>)(PPh<SUB>3</SUB>)<SUB>2</SUB>] containing a <I>C</I>,<I>O</I>-chelated tfac dianion.
