Application

tert-Butyl isocyanide was used in the synthesis of coumarines, 4H-chromenes and isoxazolines. It was also used to trap 2-cyclopropylidene-1,3-diones.

General description

Carbon dative bond formation by tert-butyl isocyanide on the germanium (100) surface has been reported. It also forms complexes with metals and inserts into metal-carbon bonds to form iminoacyls.

The addition of the strongly pi-bonding ligands CO or tert-butyl isocyanide to the low-spin five-coordinate iron(II) nitrite species [Fe(TpivPP)(NO2)]- (TpivPP = picket fence porphyrin) gives two new six-coordinate species [Fe(TpivPP)(NO2)(CO)]- and [Fe(TpivPP)(NO2)(t-BuNC)]-. These species have been characterized by single-crystal structure
