Insertion of benzyl isocyanide into a Zr–P bond and rearrangement. Atom-economical synthesis of a phosphaalkene†
Abstract
Reaction of (N3N)ZrPHPh (1, N3N = N(CH2CH2NSiMe3)33−) with PhCH2NC affords the 1,1-insertion product (N3N)Zr[C(PHPh)
NCH2Ph] (2), which thermally rearranges to the phosphaalkene-containing complex, (N3N)Zr[N(CH2Ph)C(H)
PPh] (3).
