Whereas treatment of P<sub>4</sub> with three equivalents of Na[SiPhtBu<sub>2</sub>] in thf gave the tetraphosphide Na<sub>3</sub>[P(PSiPhtBu<sub>2</sub>)<sub>3</sub>] as main product (along with, e.g., Na<sub>2</sub>[PSiPhtBu<sub>2</sub>], Na<sub>2</sub>[tBu<sub>2</sub>PhSiP–P=P–PSiPhtBu<sub>2</sub>], and Na<sub>2</sub>[P<sub>5</sub>(SiPhtBu<sub>2</sub>)<sub>3</sub>]). However, no tetraphosphide Na<sub>3</sub>[P(PSitBu<sub>3</sub>)<sub>3</sub>] was formed by the reaction of P<sub>4</sub> with three equivalents of Na[SitBu<sub>3</sub>] in thf. The triphosphide Na[tBu<sub>2</sub>PhSiP–P=PSiPhtBu<sub>2</sub>] could be obtained together with Na[PHSiPhtBu<sub>2</sub>] by protolysis of Na<sub>3</sub>[P(PSiPhtBu<sub>2</sub>)<sub>3</sub>]. When a mixture of a 3:1 reaction of Na[SiPhtBu<sub>2</sub>] and P4 was heated to 100 °C in vacuo, {Na[P(SiPhtBu2)2]}2 was generated along with Na2[PSiPhtBu2] and P<sub>4</sub>. Single crystals of Na[P(SiPhtBu<sub>2</sub>)<sub>2</sub>] were grown from a heptane solution at room temperature (monoclinic space group C2/c). 2011-11 Wagner, Matthias 2017-06-14T09:53:28Z Lerner, Hans-Wolfram
