Abstract: The main objective of this study concerns the sonochemical synthesis of 1,3-dioxolane derivatives using graphene oxide catalyst by applying two methods. In the first method, we described the synthesis of 1,3-dioxolane by ring-opening of epoxides in the presence of ketones catalyzed by graphene oxide (GO) under ultrasonic irradiation. In the second sonochemical procedure, we described the synthesis of 1,3-dioxolane derivatives by the reaction of 1,2-diols with ketones using same GO catalyst. Mild reaction conditions, high yields, short reaction times, reusability of catalyst and easy isolation of the products make the developed methods very useful.

A friendly method for the protection of diols and carbonyls catalysed by hexahydrated iron (III) chloride has been developed. This method, which consists of the transformation of diols and carbonyls to cyclic acetals, functions in mild conditions and it is efficient for a wide range of diols.

P2O5 as a dehydrating agent can be used for acetalization of carbonyl compounds. This reaction is very fast with high yield and also comparable with acetal formation by using microwave irradiation.

The peroxides (1a-e) and epoxides (2a-g) in methylene dichloride were treated with tungsten (VI) oxide and then with catalitic amounts of chlorosulphonic acid to give the corresponding 1,2,4-trioxanes (3a-r) in 10-63percent yield.The mode of decomposition of the 1,2,4-trioxanes was studied by treating a number with the following reagents: triethylamine, sodium ethoxide, lithium di-isopropylamide, Grignard and lithium reagents, lithium aluminium hydride, anthrylsodium, triphenylphosphine, and titanium tetrachloride.
