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)
