A crystalline porous metal-organic framework Cu2(BPDC)2(BPY) (BPDC=4,4'-biphenyldicarboxylate, BPY=4,4'-bipyridine) was synthesized and characterized by several techniques including XRD, SEM, TEM, thermogravimetric analysis, FTIR, atomic absorption spectrophotometry, hydrogen temperature-programmed reduction, and nitrogen physisorption measurements. The Cu2(BPDC)2(BPY) could be employed as a heterogeneous catalyst for the copper-catalyzed cross-dehydrogenative coupling reaction of DMF with 2-substituted phenols to form organic carbamates through CH activation under oxidative conditions. The Cu2(BPDC)2(BPY) offered higher catalytic activity than common copper salts such as Cu(OAc)2, CuCl, CuCl2, CuI, and Cu(NO3)2 as well as other Cu-MOFs such as Cu3(BTC)2, Cu(BDC), and Cu(BPDC). The Cu2(BPDC)2(BPY) catalyst could be facilely separated from the reaction mixture, could be recovered and reused several times without significant degradation in catalytic activity.

Transformation of relatively less reactive functional groups under catalyst-free conditions is an interesting aspect and requires a typical protocol. Herein, we report the synthesis of various primary, secondary, and tertiary amines through hydroboration of amides using pinacolborane under catalyst-free and solvent-free conditions. The deoxygenative hydroboration of primary and secondary amides proceeded with excellent conversions. The comparatively less reactive tertiary amides were also converted to the corresponding N,N-diamines in moderate yields under catalyst-free conditions, although alcohols were obtained as a minor product.

We developed a protocol for the palladium-catalyzed aminocarbonylation of aryl halides using less-toxic formamide acetals as bench-stable aminocarbonyl sources under neutral conditions. Various aryl (including heteroaryl) halides reacted with N,N-dialkylformamide acetals in the presence of a catalytic amount of tris(dibenzylideneacetone)dipalladium(0)-chloroform adduct and xantphos to give the corresponding aromatic carboxamides at 90–140 °C without any activating agents or bases in up to quantitative chemical yield. This protocol was applied to aryl bromides, aryl iodides, and trifluoromethanesulfonic acid, as well as to relatively less-reactive aryl chlorides. A wide range of functionalities on the aromatic ring of the substrates were tolerated under the aminocarbonylation conditions. The catalytic aminocarbonylation was used to prepare the insect repellent N,N-diethyl-3-methylbenzamide as well as a synthetic intermediate of the dihydrofolate reductase inhibitor triazinate.

Herein we report a robust and synthetically useful catalyst-free amination methodology by the coupling of carboxylic acids and N-substituted formamides using POCl3 as a promoter. Versatile amides with a wide array of substituent groups were prepared within only 1 h in good to excellent yields. And even multi-substituted aromatic carboxylic acids could give the desired products with satisfactory results.
