The new phosphine, PBut2Bui (L), was prepared from But2PCl and LiBui.PPh2Bui (L') was prepared from PH2PCl and LiBui.Treatment of t)2> with L' gives which does not cyclometallate even on prolonged boiling in 2-methoxyethanol.In contrast, t)2> reacts with PBut2Bui in boiling 2-methoxyethanol to give the cyclometallated complex (II, X = Cl).The corresponding bromide, iodide and acetylacetonate were prepared.With PPh3 II (X = Cl) gives which with NaBH4 gives .Na2PdCl4 with L (2 mol equivalents) gave trans-, which was converted into trans- by metathesis with KSCN.Treatment of Na2PdCl4 with L (1 mol equivalent) gave , which on heating in 2-methoxyethanol gave , as a mixture of syn- and anti-isomers.The complexes trans- and were also prepared. 1H- and 31P NMR data are given.
