allowing alkylthioethanals to be synthesized in 80-93% yields, has been developed. It comprises the hydrolysis of bis-1,1-alkoxy-2-alkylthioethanes using two-phase system water organic solvent. The method is applicable for both common aldehydes bearing lower radicals (R = Pr, Bu) and hitherto unknown highly boiling aldehydes (R = C7H15, C8H17, PhCH2). It has been found that alkylthioethanals can spontaneously
