Lee, Sang Bong published the artcileN-Benzylpyridinium salts as new useful catalysts for transformation of epoxides to cyclic acetals, ortho esters, and ortho carbonates, Recommanded Product: 2,2,4-Trimethyl-1,3-dioxolane, the publication is Chemistry Letters (1990), 2019-22, database is CAplus.
Epoxides react with aldehydes, ketones, lactones, and carbonates in the presence of N-(4-methoxybenzyl)-2-cyanopyridinium hexafluoroantimonate (I) under mild conditions to give cyclic acetals, ortho esters, and ortho carbonates. Thus, Me2CO was treated with styrene oxide in the presence of I at room temperature for 10 min. to give 93% dimethylphenyldioxolane II.
Chemistry Letters published new progress about 1193-11-9. 1193-11-9 belongs to dioxole, auxiliary class Dioxolanes, name is 2,2,4-Trimethyl-1,3-dioxolane, and the molecular formula is C6H12O2, Recommanded Product: 2,2,4-Trimethyl-1,3-dioxolane.
