A new protocol for the synthesis of contiguously substituted aromatic nitro compounds based on directed ortho-metalation followed by reaction with methyl nitrate is described.

A remarkable synergistic effect has been uncovered between ppm levels of Pd and Ni embedded within iron nanoparticles that leads to mild and selective catalytic reductions of nitro-containing aromatics and heteroaromatics in water at room temperature. NaBH4 serves as the source of inexpensive hydride. Broad substrate scope is documented, along with several other features including: low catalyst loading, low residual metal in the products, and recycling of the catalyst and reaction medium, highlight the green nature of this new technology.
Beyond directed ortho metalation: Ruthenium-catalyzed amide-directed C Ar-N activation/C-C coupling reaction of anthranilamides with organoboronates

A new, catalytic, and general methodology for the synthesis of biaryls and heterobiaryls by the cross coupling of anthranilamide derivatives (o-NMe 2 benzamides) with aryl boroneopentylates is described. The reaction proceeds under catalytic RuH2(CO)(PPh3)3 conditions driven by the activation of the unreactive C-N bond by amide directing group (DG)-Ru catalyst chelation. High regioselectivity, orthogonality with the Suzuki-Miyaura reaction, operational simplicity, and convenient scale-up are features of these reactions which may lend themselves to industrial applications.
Helix persistence and breakdown in oligoureas of metaphenylenediamine: Apparent diastereotopicity as a spectroscopic marker of helix length in solution
Clayden, Jonathan,Lemiegre, Loic,Morris, Gareth A.,Pickworth, Mark,Snape, Timothy J.,Jones, Lyn H.
supporting information; experimental part, p. 15193 - 15202 (2009/03/12)
Oligomeric ureas derived from m-phenylenediamine with chain lengths of up to seven urea linkages were made by iterative synthetic pathways. Three families were synthesized: 4 and 20, bearing a terminal chiral sulfinyl group; 24, bearing a terminal rotatio
Trapping of translocated radicals by tetrathiafulvalene radical cation
Murphy, John A.,Roome, Stephen J.
, p. 1349 - 1358 (2007/10/02)
Aryl radicals are generated by electron transfer from tetrathiafulvalene to arenediazonium salts.The aryl radicals are translocated into alkyl radicals which undergo a C-S or C-C bond formation to tetrathiafulvalene radical cation, depending on the nucleophilicity/electrophilicity of the translocated carbon radical.
