Heterogeneously catalysed synthesis of primary amines by direct amination of alcohols with ammonia has long been an elusive goal. In contrast to reported Ru-based catalytic systems, we report that Ru-MgO/TiO2 acts as an effective heterogeneous catalyst for the direct amination of a variety of alcohols to primary amines at low temperatures of ca. 100 °C without the introduction of H2 gas. The present system could be applied to a variety of alcohols and provides an efficient synthetic route for 2,5-bis(aminomethyl)furan (BAMF), an attention-getting biomonomer. The high catalytic performance can be rationalized by the reactivity tuning of Ru-H species using MgO. Spectroscopic measurements suggest that MgO enhances the reactivity of hydride species by electron donation from MgO to Ru.

The ion PhCO2--CHPh, upon collision activation, undergoes competitive losses of CO and CO2 of which the former process produces the base peak of the spectrum. Product ion and substituent effect (Hammett) studies indicate t

By using Raney Co-Al in 20% Na2CO3-D2O solution, deuterium atoms can be selectively incorporated into the benzylic position of aromatic compounds in high deuterium content.

Reactions of alkyl o-(N-methylcarbamoyl)phenyl sulphoxides 1 with various electrophiles, such as acetic anhydride, acetyl chloride, thionyl chloride and p-toluenesulphonyl chloride, have been carried out.Treatment of 1 with excess acetic anhydride in general leads to the formation of the Pummerer type rearrangement products or related products.In the reactions of 1 with acetyl, thionyl and p-toluenesulphonyl chlorides, 2-methyl-1,2-benzisothiazole-3(2H)-one, 4b, and alkyl chlorides were obtained nearly quantitatively.All these reactions can be rationalized on the basis of the initial O-acylation and subsequent either α-proton removal to result in the Pummerer rearrangement or nucleophilic attack of neighbouring carbamoyl group to afford the five-membered products 4b.
