“…Accordingly, the nature of ancillary ligands can strongly controls the lability of platinum complexes. With regard to recent reports, the investigations based on the oxidative addition of alkyl halides to platinum complexes, were carried out using complexes with nitrogen donor ligands, and phosphine‐ligated platinum (II) analogs have received less attention . However, phosphine ligands effectively provide a wide range of attractive features for the platinum complexes, by inducing specific electronic and steric properties.…”
