title: The reactivity of cyclo-(P5tBu4)- towards group 13, 14 and 15 metal chlorides: complexation and formation of cyclooligophosphanes, [cyclo-(P5tBu4)]2 and [cyclo-(P4tBu3)PtBu]2, by reductive elimination.
abstract: [Na(THF)4][cyclo-(P5tBu4)] (1) reacts with Et2AlCl and GeCl4 to give Et2Al[cyclo-(P5tBu4)](THF) (2) and, in low yield, GeCl3[cyclo-(P5tBu4)], respectively, while the reaction of 1 with SnCl2, PbCl2 or BiCl3 results in the formation of the structural isomers [cyclo-(P5tBu4)]2 (3) and [cyclo-(P4tBu3)PtBu]2 (4)(besides other cyclic phosphanes) and elemental metal.
