Abstract

Reacting Zeise's salt with the phospha(III)azene (R₃C)(R₃Si)N-P = N-CR₃ (R = CH₃) (1) one gets the platinum phospha(III)azene complex (2), Cl₂PtIL₂ (L = 1). 2 adds water and methanol to the P = N bond of the phospha(III)azene ligand with formation of 3, Cl₂Pt(PRR₂ ¹)₂ (R = (CH₃)₃SiO, R¹ = (CH₃)₃CNH) and 4, Cl₂Pt(PRR¹R²)₂ (R = CH₃O, R¹ = (CH₃)₃CNH, R² = (CH₃)₃SiNC(CH₃)₃). 2, 3 and 4 have trans configuration, 4 also forms a mixture of the meso and d, 1 isomers. For 2 a P-σ coordination of the phospha(III)- azene ligand is proposed.
