Children learn through play, and they learn more than adults might expect. Science experiments are a great way to spark their curiosity, get their minds active, and encourage them to do something that doesn’t involve a screen. 1806-29-7, C12H10O2.

The acetal formation of thioketones with several diols and phenols through metal ion-mediated desulfurization-condensation was investigated. The reactivities of 4,4?-bis(dimethylamino)thiobenzophenone) “thio-Michler’s ketone” (TMK) and xanthene-9-thione (XT) toward alpha,omega-alkanediols [HO(CH2)nOH, n = 2?4] in the presence of silver trifluoroacetate and triethylamine were compared. The reaction of TMK with glycerol, trans- and cis-1,2-cyclohexanediols, alpha,alpha’-dihydroxy-o-xylene and biphenyl-2,2-diol in the presence of silver salt gave the corresponding acetals in good yields. On the other hand, copper(I) chloride, in place of silver(I) salt, was useful for catechol and pyrogallol to give their acetals, respectively. It was thus found that thioketones are new and versatile acetalizing reagents for diols and phenols.
