Nouveaux complexes de phosphaalcènes à polarité normale et inverse

Abstract : This doctoral thesis is dedicated to the study of coordination of phosphorus ligand bearing a P=C double bond on electron-rich metals, typically Ni(0) and Pt(0). Coordination leads to an isomerization of the phosphaalkene moiety in benzophospholane by insertion of phosphorus into a C−H bond of the phosphorus-beared supermesityl. A mecanism for this reaction is proposed, which is backed by quantum calculations and which correlated observed results (especially observed intermediates). Another part of this work is dedicated to the study of coordination of inversely polarized phosphaalkenes. Those species bear one or several nitrogen atom in alpha of the carbon of the P=C double bond. Their ability to give two lone pairs was studied as well as a potential application as phosphinidene precursors.
