The use of triglycerides as an important class of biomass is an effective strategy to realize a more sustainable society. Herein, three heterogeneous catalytic methods are reported for the selective one‐pot transformation of triglycerides into value‐added chemicals: i) the reductive amination of triglycerides into fatty amines with aqueous NH3 under H2 promoted by ZrO2‐supported Pt clusters; ii) the
使用甘油三酸酯作为生物质的重要类别是实现更可持续社会的有效策略。本文报道了三种将甘油三酸酯选择性单锅转化为增值化学品的非均相催化方法:i)在Z 2 O 2支撑的Pt团簇的促进下,在H 2下,NH 3水溶液将甘油三酸酯还原胺化为脂肪胺。ii)高二氧化硅H-β(Hβ)沸石在180°C催化的气态NH 3下甘油三酸酯的酰胺化;iii)在220°C下,由Hβ促进的甘油三酸酯和气态NH 3合成腈。这些方法广泛适用于各种甘油三酸酯(C 4 –C18个骨架)成相应的胺,酰胺和腈。
An Efficient Heterobimetallic Lanthanide Alkoxide Catalyst for Transamidation of Amides under Solvent-Free Conditions
lanthanide catalysts showed high catalytic activity and a wide scope of substrates with good to excellent yields under solvent‐freeconditions. Efficient activation of the transamidation can be realized by the above complexes acting as cooperative acid–base bifunctional catalysts, which are proposed to be responsible for the higher reactivity in comparison with simple monometallic catalysts.

The smooth and neutral acylation of amines to form amides by photoactivation of N-acyl-5,7-dinitroindolines is described. An improved acylation of nitroindolines allows the convenient preparation of N-acylnitroindolines. This reaction makes possible the recycling of the nitroindoline released during the photoactivation.

carboxylic acids is a very green, efficient and sustainable method for the production of (bio-based) amines. However, with current technology, this reaction requires two to three reaction steps. Here, we report the first (heterogeneous) catalytic system for the one-pot reductive amination of carboxylic acids to amines, with solely H2 and NH3 as the reactants. This reaction can be performed with relatively cheap
Reaction of Amphipathic-Type Thioester and Amine with Hydrophobic Effect in Water

The title reaction was studied using sodium 3-(1-oxododec-1-yl)thio- and 3-(1-oxohept-1-yl)thiopropanoate with various chain lengths of amines. The yields of the amides were found to depend on both the chain length of the thioester and that of amine, suggesting the presence of hydrophobic interaction. The amides were obtained in better yields after addition of sodium fluoride. Acylation (dodecanoylation) of some hydrophobic amino acids was also studied to obtain the corresponding amides.
