Synthesis of platinum-iodo-alkyl/aryl complexes in ligand-exchange reactions: Determination of the structure of Pt{(S,S)-bdpp}(X)I complexes (X = Me, I) by X-ray crystallography

Pt{(S,S)-bdpp}(R)I (bdpp = 2,4-bis(diphenylphosphino)pentane; R = Me, Ph, Bz, 2-Tioph) complexes were formed in alkyl/aryl ligand – iodide ligand-exchange reactions by reacting the corresponding Pt{(S,S)-bdpp}R2 complexes with methyl iodide. The Pt{(S,S)-bdpp}(Me)I complex was isolated and fully characterised. The influence of the X ligand on the platinum-bdpp chelate conformation was investigated in Pt{(S,S)-bdpp}(X)I (X = I, SnCl3, Me) complex series by means of X-ray crystallography.

Graphical abstractPt{(S,S)-bdpp}(X)I (X = I, Me; bdpp = 2,4-bis(diphenylphosphino)pentane) complexes were synthesised in ligand exchange reactions and their structure was determined by X-ray crystallography. Three different platinum-bdpp chelate conformations have been identified.Figure optionsDownload full-size imageDownload as PowerPoint slide
