Pyran chemistry was reviewed in Volume 34 in our series in 1983 by J. Kuthan he and his group (J. Kuthan, P. Sebek and S. Bohm of the Prague Institute of Chemical Technology, Czech Republic) have now updated that overview. The present chapter follows on the corresponding thia-, selena-, and tellura-analogs, which appeared in Volume 59 of Advances in 1994.

At the Prague Institute of Chemical Technology, F. Jirsa studied anodic oxidation of gold [15] later he published an important paper about silver electrode for a silver-iron battery [16], Jaroslav Chloupek (1899-1975), partly with V. Danes (1907-1980) and B. Danesova, studied the electrode potential in solutions of mixed manganese salts [17], the solubility and activity coefficient of Ag2S04 in some solutions [18], the ions and deviations from the approximation of Debye-Hiickel theory [19], the liquid potentials [20], and the anomalous valency effect of strong electrolytes in aqueous solution [21].
