This review provides a survey of the key-class of Pt0 complexes of general formula [Pt(N,N'-chelate)(η2-olefin)]. The main spectroscopic, structural and chemical features are discussed, in terms of electronic and steric properties of the ancillary ligands. The versatile reactivity towards electrophiles is described as a very useful entry to PtII compounds with a wide assortment of ligands, such as halido, hydrido, hydrocarbyl, organometal, organoelement and carbene fragments, in some cases stabilised for the first time by the careful choice of the N,N'-ligand. Remarkably, the reactions can be an equilibrium, and their relevant thermodynamic parameters have also been collected, thus allowing a thorough discussion of the electronic and steric factors which affect its position.

Abstract
This review provides a survey of the key-class of Pt0 complexes of general formula [Pt(N,N'-chelate)(η2-olefin)]. The main spectroscopic, structural and chemical features are discussed, in terms of electronic and steric properties of the ancillary ligands. The versatile reactivity towards electrophiles is described as a very useful entry to PtII compounds with a wide assortment of ligands, such as halido, hydrido, hydrocarbyl, organometal, organoelement and carbene fragments, in some cases stabilised for the first time by the careful choice of the N,N'-ligand. Remarkably, the reactions can be an equilibrium, and their relevant thermodynamic parameters have also been collected, thus allowing a thorough discussion of the electronic and steric factors which affect its position.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
