Boric acid and borates form very stable complexes exceedingly rapidly with polyols10 and a-hydroxy carboxylic acids.11 These are mainly 1 1 and of type (8-V). The acidity of boric acid is thereby increased glycerol is commonly used analytically as the acid can then be titrated by aqueous NaOH. Steric considerations are very critical in the formation of these complexes. Thus 1,2- and 1,3-diols in the cw-form only, such as c/j-l,2-cyclo-pentanediol, are active, and only o-quinols react. Indeed, the ability of a diol to affect the acidity of boric acid is a useful criterion of the configuration where cis-trans-isomers are possible.
