Recent observation of the acetal species in the course of auto-amplifying Soai reaction was analysed by the formal kinetic analysis of the experimental data and DFT computations. Kinetic analysis demonstrated convincingly that the observed species cannot be a precursor of the reaction product. Hence, it is an off-loop species that is not important for the process of the chirality amplification. DFT search for a kinetically stable acetal species resulted in the location of a Zn3 cluster stabilized with three ZnOZn bridges.
