A phenyliodine(III) diacetate mediated umpolung reactivity of the tertiary amines with suitably substituted o-hydroxybenzyl and phenyl groups is exploited to facilitate o-C(sp2)-H functionalization to afford diaryl ethers. The presence of an o-
Palladium-Catalyzed Regioselective C-Benzylation via a Rearrangement Reaction: Access to Benzyl-Substituted Anilines
Amézquita-Valencia, Manuel,Alper, Howard
, p. 16774 - 16778 (2016/11/17)
An unprecedented C-benzylation rearrangement reaction, catalyzed by palladium, is reported. The reaction proceeds by rearrangement leading to the direct synthesis of para or ortho benzyl-substituted N-methylanilines. The product is obtained in high regioselectivity, without the need to use a ligand for the catalytic process.

The synthesis of the title compounds was accomplished in four steps. The synthetic route involves the preparation of Schiff's base by reacting salicylaldehyde with m-chloroaniline in EtOH. The Schiff's base was then reduced with NaBH4/MeOH. In the second step, PCl3 was reacted with p-chlorophenol/p-bromophenol in THF in the presence of Et3N to obtain P(III) dichloride derivatives. The reduced Schiff's base and dichloride derivatives were reacted in equimolar quantities in the presence of Et 3N in THF to get the cyclized product. Alkyl azides were prepared by reacting alkyl bromides with sodium azide, and then alkyl azides were treated with the cyclized product to obtain the title compounds. The structure of these novel compounds was elucidated by elemental analysis, IR, 1H, 13C, 31P NMR, and mass spectroscopy.
Zirconium borohydride - A versatile reducing agent for the reduction of electrophilic and nucleophilic substrates
Narasimhan,Balakumar
, p. 4387 - 4395 (2007/10/03)
Zirconium borohydride, a potential reducing agent, reduces acids, esters, imines to the corresponding alcohols and secondary amines in good yield at room temperature within two hours. This facile reducing property was taken advantage off in the synthesis of pheromones and some novel chiral precursors for asymmetric synthesis.
