Highly efficient and chemoselective interchange of 1,3-oxathioacetals and dithioacetals to acetals promoted by N-halosuccinimide

Highly efficient interconversion of a range of 1,3-oxathiolanes, 1,3-dithiolanes and 1,3-dithianes to their acetals at ambient temperature using N-bromosuccinimide or N-chlorosuccinimide and different types of alcohols and diols was investigated.

Single-pass reaction column system with super br?nsted acid-loaded resin

Various acid-promoted reactions gave the desired products in high yields by passing a solution of reactants through a reaction column packed with polystyrene-bound super Br?nsted acid (1) just once. Polar and nonpolar organic solvent-swellable 1 is much superior to Nafion SAC-13 (2) as a Br?nsted acid-loaded resin packed in the column.

W-bromosuccinimide (NBS) as a powerful and chemoselective catalyst for acetalization of carbonyl compounds under almost neutral reaction conditions

Highly efficient and mild acetalization of various types of carbonyl compounds was achieved using NBS under almost neutral reaction conditions. Due to the neutrality of the medium this method is especially useful for the protection of acid sensitive substrates. Thieme Stuttgart.

2,3-dichloro-5,6-dicyano-p-benzoquinone (DDQ) as a highly efficient and mild catalyst for diethyl acetalization of carbonyl compounds

Various types of structurally different carbonyl compounds in the presence of ethyl orthoformate (EtO)3CH could be efficiently converted to their diethyl acetals by using a catalytic amount (1-3 mol%) of DDQ under mild reaction conditions.

Tungsten hexachloride (WCl6), a highly efficient and chemoselective catalyst for acetalization of carbonyl compounds

Various types of aldehydes and ketones could be converted chemoselectively to their corresponding 1,3-dioxanes or diethyl acetals in the presence of catalytic amounts of tungsten hexachloride (WCl6) in good to excellent yields in CH2Cl2 or under neat conditions, respectively.

Zirconium tetrachloride (ZrCl4) catalyzed highly chemoselective and efficient acetalization of carbonyl compounds

Zirconium tetrachloride (ZrCl4) is a highly efficient and chemoselective catalyst for the acetalization, and in-situ transacetalization of carbonyl compounds under mild reaction conditions.

SYNTHESIS OF DIMETHYL ACETALS, DIETHYL ACETALS, AND CYCLIC ACETALS CATALYZED BY AMINOPROPYLATED SILICA GEL HYDROCHLORIDE (APSG*HCl)

The aminopropylated Silica-Gel hydrochloride (APSG*HCl) proved to be an efficient catalyst for the rapid conversion of carbonyl compounds in the corresponding acetals with high yields and in mild and selective conditions.In addition to the obvious advantages offered by heterogeneous catalysis, the present method results very useful when the presence of a weakly-acidic function chemically bonded on the catalyst surface (alkyl ammonium salt) is necessary (compounds which contains functions unstable in acidic media).
