The reaction of (R{sub 2}NCS{sub 2})Pt(PEt{sub 3})Cl (R = Me, Et), prepared from (Pt(PEt{sub 3})Cl{sub 2}){sub 2} and Na(R{sub 2}NCS{sub 2}), with alkyllithium or Grignard reagents yields (R{sub 2}NCS{sub 2})Pt(PEt{sub 3})(alkyl) (alkyl = Me, n-Pr, i-Pr, n-Bu, sec-Bu, i-Bu, t-Bu) complexes. These new alkylplatinum complexes are very stable and can be heated in solution at 100{degree}C for extended periods without decomposition. The reaction of (R{sub 2}NCS{sub 2})Pt(PEt{sub 3})Cl with NaBH{sub 4} yields the stable complexes (R{sub 2}NCS{sub 2})Pt(PEt{sub 3})H, which decompose only slowly at 110{degree}C. This hydride (R = Me) does not react with ethylene or phenylacetylene but will react with MeO{sub 2}CC{triple bond}CCO{sub 2}Me to yield a mixture of the E and Z isomers of (Me{sub 2}NCS{sub 2})Pt(PEt{sub 3})({eta}{sup 1}-C(CO{sub 2}Me)=C(H)CO{sub 2}Me). The reaction of (R{sub 2}NCS{sub 2})Pt(PEt{sub 3})Cl with AgBF{sub 4} and ethylene yields ((R{sub 2}NCS{sub 2})Pt(PEt{sub 3})(C{sub 2}H{sub 4}))BF{sub 4}, but these complexes are very unstable, decomposing rapidly in the absence of ethylene. The complexes (Me{sub 2}NCS{sub 2})PtLCl (L = CO, C{sub 2}H{sub 4}) are prepared by mixing the L ligand with (Pt(Me{sub 2}NCS{sub 2})Cl){sub 2}.
