Mastagli, Pierre published the artcileCatalytic transketalizations in the presence of metallic oxides, Product Details of C6H12O2, the publication is Compt. Rend. (1963), 257(3), 690-2, database is CAplus.

Me2C(OEt)2 (I) (0.2 mol), 0.5 mol ROH (R = alkyl), and 10% catalyst was refluxed 2 h., filtered, and fractionated to give Me2C(OR)2 (II). I and heptanol gave II (R = C7H15) (catalyst and % yield given): MoO3, 17; Amberlite IR 120, 12; Co2O3Co3O4 mixture, 10; WO3, 1. Using MoO3 catalyst, the following II were prepared (R, b.p./mm., nD/temperature, % yield given): Bu, 130°, 1.414/18°, 19; C5H11, 112°/15, 1.4188/17°, 46; C7H15, 160°/10, 1.4319/17°, 17; C8H17, 185°/13, 1.4347/19° 15; sec-C8H17 165°/10, 1.4358/20°, 5; C12H25, 240°/12 (m. 35°), -, 10. Traces of byproduct MeC(:CH2)OR were usually formed, but with C12H25OH, appreciable amounts of MeC(:CH2)OC12H25, b12 195°, n15D 1.4469, formed, which was reduced by Raney Ni and H to iso-PrOC12H25, b10 138°, n20D 1.4290. Good yields of ketals (structure not given), without formation of byproducts, were obtained from diols and I with MoO3 catalyst (diol, product formula, b.p., nD/temperature, % yield given): MeCH(OH)CH2OH, C6H12O2, b. 99°, 1.4038/16.5°, 43; (HOCH2)2CH2, C6H12O2, b. 124°, 1.4196/19°, 65; MeCH(OH)CH2CH2OH, C7H14O2, b. 131°, 1.4190/19.7°, 76; (HOCH2CH2)2, C7H14O2, b. 136°, 1.4277/18°, 38; HOCH2CMePrCH2OH, C10H20O2, b10 71°, 1.4320/20°, 70.
