TosMIC

Toluenesulfonylmethyl isocyanide or TOSMIC is an organic compound with the formula CH₃C₆H₄SO₂CH₂NC. The molecule contains both sulfonyl and isocyanide groups. It is a colourless solid that unlike many isocyanides, is odorless. It is prepared by dehydration of the related formamide derivative. It is used in the Van Leusen reaction which is used to convert aldehydes to nitriles or in the preparation of oxazoles and imidazoles. The versatility of TosMIC in orgnic synthesis has been documented.
