Mechanismen nucleophiler Austauschreaktionen : Ligandenaustausch an Phosphoranen und Stiboranen

Pentacovalent P and Sb compds., e.g. pentaphenyl-phosphoranes, phenyldi(biphenylylene)phosphoranes, and alkyl, phenyl, or mixed phenylalkylstiboranes, readily underwent nucleophilic ligand exchange when treated with alkyl or aryl lithium compds. The ligand exchanges increased in the order of P < As (D. Hellwinkel and Kilthau, 1966) < Sb, whereby an ate-complex mechanism was assumed. [on SciFinder (R)]

    Keywords: phosphoranes ligand exchange lithium compds; mechanism nucleophilic ligand exchange; stiboranes ligand exchange
