The synthesis of phosphorus heterocycles from tetra-tert-butyltetraphosphacubane

R. J. Baker, H. Bettentrup and C. Jones

Abstract: Tetra-tert-butyltetraphosphacubane, P₄C₄^tBu₄, reacts with water in the presence of `GaI' to yield two products, namely 4,6,7,8-tetra-tert-butyl-1,2,3-triphospha-5-phosphoniatetracyclo[3.2.1.0^2,4.0^3,8]oct-6-ene tetraiodogallate(III), (C₂₀H₃₇P₄)[GaI₄], and triiodo(3,5,7,8-tetra-tert-butyl-1,2,4 [bold lambda] ⁵,6-tetraphosphatetracyclo[4.1.1.0^2,5.0^7,8]octan-4-one)gallium(III), [GaI₃(C₂₀H₃₈OP₄)], both of which have been structurally characterized. The X-ray crystal structure determination of the former compound shows it to be an ion-separated salt, while the latter compound is a neutral phosphinite complex of GaI₃.

Formula: (C₂₀H₃₇P₄)[GaI₄] and [GaI₃(C₂₀H₃₈OP₄)]
