General description

Isopropyl isocyanide is an alkyl isocyanide.

Application

Isopropyl isocyanide may be used in the preparation of:
  • Ugi ligand A2C11I1, which is employed in the solid-phase Ugi synthesis.
  • Pentafluorophenyl (PFP) functional monomers, via Passerini reaction.
  • Dinuclear copper complex [Cu2(μ-PiPr2bipy)2{μ-CNCH(CH3)2}](PF6)2 [PiPr2bipy = 6-(diisopropylphosphanyl)-2,2′-bipyridine].
  • (3E)-(Imino)thiaisoindoline 1,1-dioxide derivative.
  • N,N′-diisopropylcarbodiimide (DIC) analog via reaction with propan-2-amine.
  • 1-t-butyl-2-isopropyldiaziridinone via reaction with 2-methyl-2-nitrosopropane
  • isopropyl isocyanate via reaction with ozone
  • 1-phthalimidoazetidines via [1+3]cycloaddition reaction with 1-pththalimidoaziridines
