Summary
The cycloplatinated species,cis- andtrans-[Pt(Pmes2· C6H2Me2CH2)Cl(NC5H4X)] (X = CN, CO2Me, H, Ph, Me,t-Bu and NMe2), are formed byin situ chloro-bridgecleavage of [Pt(Pmes2C6H2Me2CH2)Cl]2.Cis - andtrans-influences exerted by NC5H4X show apparently exactly opposite correlations with ligand basicities and inverse correlation with each other. High basicity corresponds to strongtrans-influence but weakcis-influence andvice versa. These relationships are rationalized in terms of σ-inductive effects.
