Abstract

The synthesis and crystal structures of the alkali-metallated organophosphine oxides [{Ph₂P(O)CH₂}K · 18-crown-6] (1) and [{Ph₂P(O)CH₂}Na · 15-crown-5] (2) are reported. In addition the insertion reaction of an isonitrile into the C-Li bond of [{Ph₂P(O)CH₂}Li] is reported and the crystal structure of the resulting tetrameric complex [Ph₂P(O)CH{double bond, long}CHN(Cy)Li]₄ (3) (Cy = Cyclohexyl) described.
