Supported RuB amorphous alloy mediated 1 atm hydrogenation of carbonyl compounds under ambient temperature

Treatment of 2-Mercaptothiazoline, 2-Mercaptobenzimidazole, 2-Mercapto-1- methylimidazole with [M2(CO)10] (M = Re and Mn) at ambient temperature in presence of decarbonylating reagent Me3NO give the complexes [Mn2(?-?2-C3H4NS2)2(CO)6] (1), [Re2(?-?2-C3H4NS2)2(CO)6] (2), [Mn2(?-?2-C7H5SN2)2(CO)6] (3), [Re2(?-?2- C7H5SN2)2(CO)6] (4), [Re2(?-?2-C4H5N2S)2(CO)6] (5) and [Re2(?1-C4H5N2SH)(CO)9] (6) respectively. All the compounds have been characterized by IR, 1H NMR and mass spectral data. The heterocyclic ligands are expected to be coordinated to two or single metal atom through the nitrogen and sulfur atoms or via only sulfur atom.DOI: http://dx.doi.org/10.3329/jbcs.v25i1.11775 Journal of Bangladesh Chemical Society, Vol. 25(1), 62-70, 2012>

Aldehydes And Ketones

Aldehydes or ketones reacted with acetic anhydride in dichloromethane at ambient temperature to produce gem-diacetates in good to excellent yields in the presence of gallium triiodide, which was generated in situ from gallium and iodine. This catalyst was also useful for the deprotection of carbonyl compounds in the presence of water.

Ch Acids

Multicomponent reactions involving polyfunctional 4-amino-5-carboxamido-1,2,3-triazole and cyclic carbonyl-containing CH-acids were studied under conventional thermal heating, microwave and ultrasonic irradiation. The features of the reactions studied were discussed and the optimized procedures for the synthesis of final triazolopyrimidines were elaborated. In contrast to the similar MCRs of numerous other aminoazoles, a change of direction of the heterocyclizations in the case of 4-amino-5-carboxamido-1,2,3-triazole was not observed when microwave or thermal heating was substituted by ultrasonication at ambient temperature.
