TosMIC (toluenesulfonylmethyl isocyanide) is an
nitriles or in the preparation of oxazoles[2] and imidazoles.[3] The versatility of TosMIC in organic synthesis has been documented.[4] It is a fairly strong carbon acid, with an estimated pKa of 14 (compared to 29 for methyl tolyl sulfone), the isocyano group acting as an electron acceptor of strength comparable to an ester group.[5]
