文摘

Two synthetic routes to bifunctional P(V)/P(V) compounds of the type EPR₂NP(I)R₂ have been developed. The reaction of Li[EPⁱPr₂NPⁱPr₂] with one molar equivalent of I₂ produces EPⁱPr₂NP(I)ⁱPr₂ (3a-I, E = Se; 3b-I, E = Te). Alternatively, the oxidation of Na[N(P^tBu₂)₂] with I₂ in tetrahydrofuran (THF) generates the P(III)/P(V) compound ^tBu₂PNP(I)^tBu₂ (6′-I) which, on treatment with elemental selenium or tellurium in THF, yields EP^tBu₂NP(I)^tBu₂ (3a′-I, E = Se; 3b′-I, E = Te). The acyclic compounds 3a-I, 3a′-I, 3b-I, 3b′-I, and 6′-I have been characterized in solution by multinuclear (¹H, ³¹P, ⁷⁷Se, and ¹²⁵Te) NMR spectroscopy and in the solid state by X-ray structural determinations.
