European Journal of Organic Chemistry, Volume 27, Issue 7, February 19, 2024.Flexible bis‐catecholate podand‐type ligands of various lengths were synthesized. Upon reaction with boric acid and a hydroxide alkaline solution, a spiroborate node forms and the alkali cation is wrapped by the flexible spacer. Influence of the spacer's length and the alkali cation size on the formation of monomeric or oligomeric spiroborate compounds
