The possible role of clays in prebiotic evolution was studied using the primitive Earth model in which aqueous solutions of HCN and diaminomaleonitrile (I) react with clay mineral sediments. The reaction of 0.1M HCN and dilute solutions of I at pH 8-9 and 25° in the presence of suspensions of montmorillonite (bentonite) clays were investigated. Montmorillonite clays inhibited the oligomerization of aqueous solutions of HCN. Yields of colored oligomers, urea, and I were all diminished by clays, but the rate of loss of cyanide was not significantly decreased. The inhibition of oligomer formation was due to the clay-catalyzed decomposition of I. The absence of strong binding of I to clays was suggested by the failure to detect I when a clay that was incubated with I was washed with spermidine (6 × 10-3 g/L). I did not simply bind to the clays as the bulk of radioactivity was recovered from the supernatant in the reaction of I–14C with montmorillonite. The clay-catalyzed decomposition of I was observed when montmorillonite from 2 different sources was used and with a variety of homoionic montmorillonites and bentonites. A modification of the established procedure for using the cyanide electrode for cyanide analyses was used to follow the release of HCN from I. This new method could be used in both the acidic and basic pH range and did not result in the destruction of I by the reagents used for the anal. Quant. anal. of the reaction solution from the clay-catalyzed decompositions of I revealed the formation of 1-2 equiv HCN/mol I. The possible significance of these clay-catalyzed reactions in prebiotic evolution is discussed.
