"An NMR study on the reaction of [(κ²-P,N)-Ph₂PCH₂CH₂NMe₂]PtMe₂ with activated chlorocarbons: C-Cl and C-C activation, followed by C-N cleavage of the phosphinoalkylamine ligand and formation of an ylide complex";
Monatshefte für Chemie, 145 (2014), 4; S. 577 - 584.

Reaction of [(κ²-P,N)-Ph₂PCH₂CH₂NMe₂]PtMe₂ with either ethyl chloroacetate or benzyl chloride results in complex reaction mixtures, which were investigated by a combination of NMR techniques. The reactions are initiated by oxidative addition of either the C-Cl bond or of the C-CH₂Cl bond, respectively. The latter is followed by a rearrangement of the intermediate Pt(IV) complex with concomitant C-N bond cleavage of the phosphinoalkylamine ligand and formation of the ylide complexes Pt[CH₂=PPh₂(vinyl)](NMe₂R)Me₂ (R = COOEt or Ph).
