Schiltz, Pauline published the artcileCobalt Complexes Supported by Phosphinoquinoline Ligands for the Catalyzed Hydrosilylation of Carbonyl Compounds, HPLC of Formula: 1468-83-3, the main research area is phosphinoquinoline cobalt complex preparation hydrosilylation ketone catalyst; alkoxysilane preparation hydrosilylation ketone acetophenone cobalt phosphinoquinoline catalyst; crystal mol structure cobalt phosphinoquinoline neutral cationic complex; P,N Ligand; catalysis; cobalt complexes; hydrosilylation; phosphinoquinoline.
Alkoxysilanes ArCHMeOSiHPh2 were prepared by hydrosilylation of acetophenones ArCOMe with SiH2Ph2 catalyzed by cobalt(II) 8-phosphinoquinoline (8-R2Pquin, L; R = iPr, Ph) complexes [(8-R2Pquin)CoBr2] and [(8-R2Pquin)2CoBr][PF6]. P,N phosphinoquinoline based ligands differing by the nature of the phosphorus substituent (iPr, Ph) were employed to synthesize a series of cobalt(II) complexes ([LCoBr2], [L2CoBr](PF6) and [L’2CoBr](PF6)). The complex [(8-Ph2Pquin)2CoBr][PF6] was obtained in high yield and characterized among others by X-ray anal. and elemental anal. Complex [(8-iPr2Pquin)2CoBr][PF6] showed a very good catalytic activity for the hydrosilylation of various ketones. The catalysis proceeds at a low catalytic loading (1 mol %) with only 1 equiv of Ph2SiH2 in mild conditions and was efficient with aliphatic or aromatic ketones giving moderate to excellent yields of the corresponding silylated ether.
