Compuestos de fosfito de trialilo con iones metálicos de configuración d8

Abstract

All the attempts to prepare complexes of triallyI phosphite with Pt (II) were unsuccessful. However, the reactions of this ligand with Rh (1) and Pd (II) ,take place and synthesis condi.tions are described. The composition and nature of the insulated complexes was elucid·ated by elemental analysis, molecular weight measurements and infrared and nuclear magnetic resonanse data. The triallylphosphite reaction with RhCI goes to the synthesis of chloro (triallylphosphite) rhodium (1), with all the olefin groups coordinated to the rhodium, but with Rh el (PPh3) the trans-chlorocarbonYI bis (Triphenylphosphine) rhodium (1) is insulated. On the other hand, equivalen,t amounts of (CfiH5CN)2PdCI and ligand react ,to g:ve bisallyldi-f L--chloropalladium (Il).
