We have systematically studied the reactions of acetalization and found that high reaction efficiency can be achieved using cheap and readily available organic Eosin Y as catalyst. The reaction proceeds smoothly under house bulbs and shows excellent functional group tolerance. The substrates of the reaction system are compatible with aromatic aldehydes, aliphatic aldehydes, aromatic ketones, and cyclic ketones with high yields.

Paragraph 0092-0097, (2017/05/26)
The invention discloses a green synthesis method of an acetal-type or ketal-type compound. A carbonyl compound is used as a raw material, a hydrogen-loaded compound is used as a catalyst, then an alcohol substance is added, a reaction is performed to generate the acetal-type or ketal-type compound. The synthesis method is simple and convenient, is high in conversion rate and yield, is safe and stable, has low toxicity and is easy to operate; the used catalyst is simple to prepare, and is cheap and easy to obtain; the reaction process is mild and efficient; the product is easy to separate and purify; the green synthesis method has a wide substrate application range, can be used for synthesizing acetal and ketal spices, and has potential industrial application value.

The bis-allylation of ethylene ketal and catechol ketal derivatives of 2,5-hexanedione occurred with a great stereoselectivity. The tetraallylation of bis-catechol ketal derivatives of 2,5-hexanedione and 2-methyl-1,3- cyclohexanedione or the diallylation of 4-phenylbutan-2-one derivatives arise in good yields and these compounds were suitable substrates for ring-closing metathesis leading to 4,4-dialkylcyclopentenes. Condensation of 1,8-bistrimethylsilyl-2,6-octadiene (Bistro) with 4-phenylbutan-2-one catechol ketal derivatives or 2-methylcyclohexan-1,3-dione mono catechol ketal afforded in good yields cyclic and tricyclic products 12 or 23, respectively.
