DOI: 10.1039/C4QO00272E, Highlight
Beyond classic Nozaki-Hiyama-Kishi reactions, a low-cost and low-toxicity chromium(II) salt is shown recently to have the capability to catalyze the cross-couplings of C–X and C–H bonds with Grignard reagents. It...
 
Org. Chem. Front., 2015, Advance Article
DOI: 10.1039/C4QO00246F, Research Article
The first example of Pd-catalyzed aryldifluoromethylation of arylboronic acids with readily available aryldifluoromethyl bromides has been described. Preliminary mechanistic studies revealed that a Pd(0)Ln-initiated single electron transfer (SET) pathway is involved in the catalytic cycle.

DOI: 10.1039/C4QO00256C, Research Article
Using a combination of ketones and Selectfluor to mimic α-fluoroketones, formal fluorine-atom-transfer radical addition (F-ATRA) reactions were successfully developed in high efficiency.
 
Org. Chem. Front., 2015, Advance Article
DOI: 10.1039/C4QO00244J, Research Article
From themed collection Celebrating the 80th Birthday of Professor Ei-ichi Negishi
A novel synthesis of 1H-indazoles via copper-catalyzed cross-coupling/cyclization of 2-bromoaryl oxime acetates and amines is reported.
 
Org. Chem. Front., 2015, Advance Article
DOI: 10.1039/C4QO00238E, Research Article
Allylic amination of allylic carbonates with ammonia gas or aqueous ammonia was successfully carried out using (SIPr)Pd(allyl)Cl as the catalyst and Ph3P, which is essential for the reaction.

Org. Chem. Front., 2014, Accepted Manuscript
DOI: 10.1039/C4QO00295D, Research Article
The chiral iminopyridine oxazoline (IPO) ligands were designed, synthesized and utilized for the first cobalt-catalyzed highly regio- and enantioselective anti-Markovnikov hydroboration of 1,1-disubstituted aryl alkenes. This novel IPO ligands will...
 
Org. Chem. Front., 2014, Accepted Manuscript
DOI: 10.1039/C4QO00245H, Review Article
This review highlights the recent applications of chiral N-tert-butanesulfinyl imines and chiral diene ligands, with bicyclo[3.3.0]octadiene and dicyclopentadiene skeletons, in asymmetric chemical transformations. The chiral sulfinamide-olefin products from allylation of...
 
Org. Chem. Front., 2015, Advance Article
DOI: 10.1039/C4QO00251B, Research Article
Alkylarylation of N-arylacrylamides with alkyl halides through selective scission of the C(sp3)–H bond adjacent to halide atoms is presented.
 
Org. Chem. Front., 2015, Advance Article
DOI: 10.1039/C4QO00250D, Research Article
A novel one-step synthesis of both symmetric and unsymmetric 2,2′-bisoxazoles starting from simple acyclic α-isocyanoacetamides was achieved.
 
Yun-Long Ji, Jin-Hong Lin, Ji-Chang Xiao and Yu-Cheng Gu
Org. Chem. Front., 2015, Advance Article
DOI: 10.1039/C4QO00240G, Research Article
Copper-catalyzed tandem trifluoromethylation/cyclization of internal alkynes with Umemoto's reagent leading to 3-trifluoromethyl-1,2-dihydronaphthalene derivatives in moderate to good yields is described.
