## Abstract In contrast to methyl 2‐lithioisobutyrate (I), __tert__‐butyl 2‐lithioisobutyrate (A) in tetrahydrofuran (THF) appears to have one form only, irrespective of concentration (0,1‐0,8 mol/L) or temperature (203–273 K). According to its relaxation characteristics, this form probably is a te
