[Na(THF)4][cyclo-(P5tBu4)]
(1) reacts with Et2AlCl and GeCl4 to give Et2Alcyclo-(P5tBu4)}(THF)
(2) and, in low yield, GeCl3cyclo-(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.
