The radiolysis of methanol in the presence of air as well as of pure oxygen (1 to 5atm) was investigated, the yields of the major products: carboxylic acids (by far predominantly formic acid), oxalic acid, formaldehyde and glycolaldehyde were determined as a function of the absorbed dose. In addition small amounts (G≤0.05) of glyoxal, glyoxalic acid and glycolic acid were also detected. Based on the results a possible reaction mechanism is presented.

Synthesis of RNA nucleobases from formamide is one of the recurring topics of prebiotic chemistry research. Earlier reports suggest that thymine, the substitute for uracil in DNA, may also be synthesized from formamide in the presence of catalysts enabling conversion of formamide to formaldehyde. In the current paper, we show that to a lesser extent conversion of uracil to thymine may occur even in the absence of catalysts. This is enabled by the presence of formic acid in the reaction mixture that forms as the hydrolysis product of formamide. Under the reaction conditions of our study, the disproportionation of formic acid may produce formaldehyde that hydroxymethylates uracil in the first step of the conversion process. The experiments are supplemented by quantum chemical modeling of the reaction pathway, supporting the plausibility of the mechanism suggested by Saladino and coworkers.
