The dilithiated products 2 a, b are obtained from the 2,5‐dihydro‐lH‐boroles 1 a, b at room temperature if lithium 2,2,6,6‐tetramethylpiperidide (LiTMP) is used as base: with sterically less bulky lithium amides, borates are formed. 2b ·TMEDA is present in the crystal as a centrosymmetric dimer with two pentahapto‐bound Li atoms per unit.
