Direct Conversion of Alcohols to Acetals and H2 Catalyzed by an Acridine-Based Ruthenium Pincer Complex
TL;DR: Ruthenium complex RuHCl(A-(i)Pr-PNP)(CO) (1) catalyzes the dehydrogenative coupling of alcohols to form esters and may involve hemiacetal dehydration to form an enol ether followed by alcohol addition to the double bond.

Microwave-assisted preparation of 1-butyl-3-methylimidazolium tetrachlorogallate and its catalytic use in acetal formation under mild conditions
Yong Jin Kim,Rajender S. Varma +1 more
TL;DR: In this paper, Butyl-3-methylimidazolium tetrachlorogallate, [bmim][GaCl4], prepared via microwave-assisted protocol, was found to be an active catalyst for the efficient acetalization of aldehydes under mild conditions.

Efficient acetalization of benzaldehydes using UiO-66 and UiO-67: Substrates accessibility or Lewis acidity of zirconium
TL;DR: In this paper, the performance of Zr 6 O 4 (OH) 4 clusters connected by organic linkers of 1,4-benzenedicarboxylate (UiO-66) and biphenyl-4, 4,4′-dicaraboxylates (uO-67) was investigated for benzaldehyde acetalization in methanol for an hour at r.t. (28°C).

Cobalt(II) chloride catalyzed acylation of alcohols with acetic anhydride: scope and mechanism
TL;DR: Cobalt(II) chloride catalyzes the acetylation of a variety of alcohols with acetic anhydride in excellent yield and can be selectively acylated in the presence of secondary and tertiary ones.
