A novel heterogeneous copper catalyst has been developed by supporting copper nanoparticles on activated charcoal via in situ reducing copper(II) with aqueous hydrazine as reductant. The characterization of Cu/C catalyst showed that the Cu0 nano-particles were formed on the surface of charcoal. This catalyst displayed good catalytic activities toward the N-arylation of primary amides and lactams with aryl iodides.

Combining Eosin y with Selectfluor: A Regioselective Brominating System for Para-Bromination of Aniline Derivatives
Huang, Binbin,Zhao, Yating,Yang, Chao,Gao, Yuan,Xia, Wujiong
, p. 3799 - 3802 (2017/07/26)
A mild, metal-free, and absolutely para-selective bromination of aniline derivatives has been developed in excellent yields, wherein the organic dye Eosin Y is employed as the bromine source in company with Selectfluor. Neither air nor moisture sensitive, this facile reaction proceeds smoothly at room temperature and completes within a short time. Mechanistic studies indicate a radical pathway; therefore, the existence of an in situ generated brominating reagent, "Selectbrom", is postulated, which may reasonably account for the unique regioselectivity for the para-bromination of N-acyl- as well as N-sulfonylanilines.

Polyaromatic scavenger reagents (PAHSR): A new methodology for rapid purification in solution-phase combinatorial synthesis
Warmus, Joseph S.,Da Silva, Marianne I.
, p. 1807 - 1809 (2007/10/03)
(Formula presented) A new method of purification of solution-phase combinatorial libraries has been developed. Development of a chemically inert polyaromatic anchor with a reactive "scavenger reagent" (PAHSR) allows unreacted reagents and impurities to be removed from a reaction by absorption of the PAHSR to charcoal and simple filtration.

Nucleophilic substitution reactions of benzoic anhydrides, in which one of the rings is substituted, with anilines were investigated in methanol.The product-formation step coincides with the rate-limiting step so that the two rate constants, kXY and kXZ, for the competitive reaction pathways can be dissected.The two cross-interaction constants, ρXY and ρXZ, especially an unusually large magnitude of the latter, indicate that the reaction proceeds by a frontside SN2 attack on either one of the carbonyl carbon with a strong interaction between the nucleophile (X) and the leaving group (Z).The mechanism is also supposed by the trends in the activation parameters.
