Different types of products can be obtained by addition of protic acids HX (X=Cl, BF4) to Pt(0) species of general formula [Pt(ol)(N-N)] (ol=olefin; N-N=N,N-chelate) according to the features of the two coordinated ligands. The typical attainment of four-coordinate hydrocarbyl derivatives by insertion of the alkene into the Pt-H bond is compared with the recently reported isolation of stable five-coordinate hydrides. The nature of the final product is also related to the coordinating ability of the X group. A general mechanism for the addition process is proposed.

Abstract
Different types of products can be obtained by addition of protic acids HX (X=Cl, BF4) to Pt(0) species of general formula [Pt(ol)(N-N)] (ol=olefin; N-N=N,N-chelate) according to the features of the two coordinated ligands. The typical attainment of four-coordinate hydrocarbyl derivatives by insertion of the alkene into the Pt-H bond is compared with the recently reported isolation of stable five-coordinate hydrides. The nature of the final product is also related to the coordinating ability of the X group. A general mechanism for the addition process is proposed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
