Abstract:

A facile and efficient method for the preparation of 1,1-diacetates of aldehydes is improved. The acidified kaolin with sulfuric acid (2 % w/w) catalyzed 1,1-diacetates formation from aldehydes in solvent-free conditions. Both aromatic and aliphatic aldehydes gave high yields (85-95 %) of the corresponding 1, 1-diacetates. Advantages of this method are the use of inexpensive and selective catalyst, with high yields in simple operation, and short reaction time under solvent-free conditions.

4-Sulfobenzoic Acid as an Efficient Catalyst for the Preparation of 3,4-dihydropyrimidin-2-(1H)-ones Under Solvent-free Conditions

In this research, one-pot three-component synthesis of 3,4-dihydropyrimidin-2-(1H)-ones havebeen developed using Biginelli reaction from the interaction between ethyl/methyl acetoacetate,aromatic aldehydes, and urea/thiourea in the presence of 4-sulfobenzoic acid as a new, effective,inexpensive, and available bronsted acid. Avoidance of toxic and dangerous solvents, easy isola...

Dipyridine cobalt chloride as an efficient and chemoselective catalyst for the synthesis of 1,1-diacetates under solvent-free conditions

1,1-Diacetates(acylals) were prepared by direct condensation of various aldehydes with acetic anhydride using dipyridine cobalt chloride (CoPy2Cl2) as an efficient and green catalyst under solvent-free conditions at room temperature. The important features of this catalyst method are that the catalyst is solid, stable at high temperatures, soluble in water, stable in air, immiscible in common o...
