Synthesis of new (σ2-N,N′-diazadiene)(η2-alkene)platinum(0) compounds

摘要: Abstract Novel, thermally stable, dark-red to orange Pt 0 (σ 2 - N , ′-diazadiene)(η -alkene) compounds have been synthesized in good yields from (COD) or (NBE) 3 by stepwise substitution of the respective dienes alkenes an electron-poor alkene (dimethyl fumarate, maleic anhydride fumaronitrile), followed appropriate diazadiene ligand dry diethyl ether at 20 °C (diazadiene=various ′-disubstitued-1,4-diaza-1,3-dienes). The complex Pt(DBA) is less suited as a precursor for synthesis compounds. These zerovalent Pt(diazadiene)(η constitute useful category starting materials synthetic organoplatinum chemistry and catalysis.
