| Abstract: | Hydrozirconation of the eta 2-phosphaalkyne complex Pt(dppe)(eta 2-tBuCP)] with ZrHCl(eta 5-C5H5)2], followed by treatment with the chlorophosphaalkene ClP=C(SiMe3)2 affords the eta 2-2,3-diphosphabutadiene complex Pt(dppe)(eta 2-tBuC(H)=PP=C(SiMe3)2]. In the presence of Pt(PPh3)2] the latter undergoes an addition reaction with water to afford the structurally characterised Pt(II) complex Pt(dppe)(tBuCH2P(O)HPC(SiMe3)2]. |
