  Synthesis and Structure of K⁺[ⁱPrNCP]^-, a 1-Aza-3λ³-phospha-3-allenide

  摘要：

  2-Isopropyl(trimethylsilyl)amino-1 lambda(3)-phosphaalkyne 1 reacts with potassium tert-butoxide to form potassium 1-isopropyl-1-aza-3 lambda(3)-phospha-3-allenide (2). This compound was structurally characterized as the corresponding 18-crown-6 ether complex 3. The molecular structure of 1 was also determined in order to compare the bonding situation in the anion and the neutral lambda(3)-phosphaalkyne. Compound 3 contains a nitrogen-carbon-phosphorus group for which the parameters were shown by X-ray structural analysis and quantum chemical calculations to lie between the extrema N-C equivalent to P and N=C=P, suggesting reactivity typical of an ambident anion. This is indeed the case, as subsequent reaction of 2 with chlorotrimethylsilane at nitrogen regenerates the lambda(3)-phosphaalkyne 1; with chlorotriphenylsilane the new derivative 4 is formed. In contrast, chlorotrimethylstannane reacts at phosphorus, giving the 1-aza-3 lambda(3)-phosphaallene isopropyliminomethylidene(trimethylstannyl)phosphane 5.
