pseudo-basen.

1899 Jrnl. Chem. Soc. 76 i. 400 Pseudo-bases are substances which, by isomeric change, are capable of giving a true base of the ammonium hydroxide type from which the salts are derived.

1951 C. R. Noller Chem. Org. Compounds xxx. 591 The N-alkyl-α-pyridones are obtained by the oxidation of the quaternary hydroxides. These strong bases appear to be in equilibrium with the α-hydroxydihydropyridines, which are called pseudo bases.

1960 K. W. Bentley Natural Pigments i. 14 The α- and γ-pyranols are, in fact, pseudo bases, forming a salt and water on treatment with acid.

1990 Amer. Jrnl. Bot. 77 453/1 Differences in anthocycanin production and colorless anthocycanin pseudo-base synthesis between terrestrial and aquatic plants.

1906 Jrnl. Amer. Chem. Soc. 28 911 The pseudoacid pseudobasic nature of the proteins is considered to be a matter of such importance that it is extensively discussed.

1921 Jrnl. Chem. Soc. 119 1470 One of the more characteristic reactions of pseudo-basic carbinols is the formation of ethers by simple treatment with alcohols.

1978 Jrnl. Physical Chem. 82 653/2 The appearance of the radical cation in aqueous solution is conjugated with the presence of the OH adduct via the pseudobasic equilibria A, B, and C.

1927 Ann. Rep. Progr. Chem. 24 115 The hydroxide ion tends to co-ordinate with positive carbon, whereas very stable anions like chloride..tend to retain their ionic condition..: thus arises the phenomenon of pseudo-basicity.

1967 Jrnl. Amer. Chem. Soc. 89 66/1 The addition of a third benzene ring gives a further increase in pseudo-basicity.
