A borrowing carbonate-enabled allylic cross-amination reactions employing allylic alcohol were discovered via merging acyl/allyl C-O bonds activation under nickel catalysis. The key component of this protocol is the ability of nickel [Ni(II)-Ni(0)] to execute a relay process via the nucleophilic trapping of the generated acyl Ni complex, resulting from the acyl C-O bond cleavage of dialkyl carbonates, followed by selective allylic C-O bond activations (allylic C-O vs alkyl C-O vs acyl C-O) to yield pi-allyINi-complexes. The finding truly represents Ni-catalyzed green allylic amination reactions under additive(s)-free conditions with excellent chemo- (N vs O), regio- (linear vs branched), and stereoselectivity (E vs Z) with a wide range of fundamentally challenging N-heterocycles and allylic alcohols. The reaction is scalable, does not require harmful reaction media and a globe box, and is successfully applied to the scale-up synthesis of pharmaceuticals (cinnarizine, flunarizine, and naftifine) with promising yields.

A hypercrosslinked ultramicroporous and ordered organic polymer network was synthesized from a planar trimer indole building block called triazatruxene (TAT) through anhydrous FeCl3 catalyzed Friedel-Crafts alkylation using methylal as a crosslinker. The polymer network is stable in a variety of chemicals and thermally durable. The hypercrosslinked network TATHCP shows a high BET (Brunauer-Emmet-Teller) specific surface area of 997 m(2) g(-1) with CO2 uptake capacity of 12.55 wt % at 273 K, 1.1 bar. Gas selectivities of 38.4 for CO2/N-2, 7.8 for CO2/CH4, 40.6 for CO2/O-2, and 32.1 for CO2/CO were achieved through IAST calculation. The PXRD analysis has revealed that TATHCP has a fully eclipsed structure in full agreement with Pawley refinement. The ordered 2D layers provide anisotropy that could be used in catalysis and thermoelectric measurements. After loading with Pd(II), TATHCP-Pd showed high catalytic activity in Suzuki-Miyaura cross coupling reaction with a wide range of reagents and excellent reaction yields of 90-98% with good recyclability. The structure of TATHCP-Pd was found to have two independent molecules of Pd(OAc)(2) in the asymmetric unit cell which are arranged between two TATHCP layers. Thermoelectric properties of TATHCP showed a high Seebeck coefficient and ZT, a first and promising example in HCPs with applications in all-organic thermal energy recovery devices.

We demonstrate the broad applicability of the annulation protocol combining, in one pot, a direct arylation and cross aldol condensation for the straightforward synthesis at gram-scale of pi-extended thiophene-based scaffolds. The regiospecific direct arylation drives the subsequent cross-aldol condensation proceed under the same basic conditions, and the overall protocol has broad applicability in the synthesis of extended aromatics wherein the thiophene ring is annulated with furans, pyridines, indoles, benzothiophenes, and benzofurans. These scaffolds can be further elaborated into pi-extended, highly fluorescent oligomers with a central deficient benzothiadiazole unit with up to nine aromatic rings through coupling reactions.

A ruthenium(II)-catalyzed deoxygenative transfer hydrogenation of amides to amines using HCO2H/NEt3 as the reducing agent is reported for the first time. The catalyst system consisting of [Ru(2-methylallyl)(2)(COD)], 1,1,1-tris(diphenylphosphinomethyl) ethane (triphos) and Bis(trifluoromethane sulfonimide) (HNTf2) performed well for deoxygenative reduction of various secondary and tertiary amides into the corresponding amines in high yields with excellent selectivities, and exhibits high tolerance toward functional groups including those that are reduction-sensitive. The choice of hydrogen source and acid co-catalyst is critical for catalysis. Mechanistic studies suggest that the reductive amination of the in situ generated alcohol and amine via borrowing hydrogen is the dominant pathway.
