N-Methyliminodiacetic acid is an organic compound with the formula CH3N(CH2CO2H)2. It is a white solid, which as its conjugate base CH3N(CH2CO2)2 is used as a chelating agent for iron.[2] It is a component of organoboron reagents as well.[3]

Synthesis and reaction

[edit]

It is prepared from imidodiacetic acid by N-methylation using the Eschweiler–Clarke reaction:[4]

MIDA boronates are derivatives with the formula CH3N(CH2CO2)2BR, where R is a cross-coupling partner.[5]
