Descripción general

tert-Butyl isocyanate undergoes [2+2] cycloaddition reaction with phosphagermaallene to yield 1-oxa-2-germacyclobutane. It also undergoes cycladdition reaction with molybdenum dioxo bis(aryloxide) complex to form novel 16-electron molybdenum oxo-imido bis(aryloxide) complex. It reacts with aluminum dihydride in the presence of trace amounts of water to yield terminal hydroxide containing dinuclear alumoxane.

Aplicación

tert-Butyl isocyanate can be used:
  • In the preparation of isocyanate-treated graphite oxides (iGOs) which can be exfoliated in polar aprotic solvents to obtain graphene oxide nanoplatelets.
  • To modify metal-organic frameworks, postsynthetically, to obtain microporous urea-functionalized frameworks.
  • To the synthesis of terminal hydroxide containing dinuclear alumoxane from aluminum dihydride.

Phosphagermaallene Tip(tBu)Ge=C=PMes* 1 (Tip=2,4,6-triisopropylphenyl, Mes*=2,4,6-tri-tert-butylphenyl) reacts with phenyl isocyanate and tert-butyl isocyanate by a [2+2] cycloaddition that involves the Ge=C and C=O double bonds to afford 1-oxa-2-germacyclobutanes 2 and 3. With N,N'-dicyclohexylcarbodiimide, a [2+2] cycloaddition is observed between the Ge=C
