Ruthenium-Catalyzed Functionalization of Aryl Carbon-Oxygen Bonds in Aromatic Ethers with Organoboron Compounds

The ruthenium-catalyzed reaction of aryl ethers having a carbonyl group at the ortho position to the ether group with organoboronates (R?B(OCH2CMe2CH2O), R = aryl, alkenyl, and alkyl) resulted in site-selective C?C bond formation. Among the transition metal complexes screened, the RuH2(CO)(PPh3)3 complex showed the highest activity. Several aromatic ketones having methoxy or phenoxy groups at the ortho position can also be used in this coupling reaction. A variety of arylboronates containing electron-donating (NMe2, OMe, methyl, and vinyl) and -withdrawing (F and CF3) groups reacted with methoxy ketones to give the corresponding coupling products in high yields.

supporting information, p. 1943 - 1945 (2014/03/21)
A method for oxidative kinetic resolution of racemic alcohols catalyzed by chiral nitroxyl radical (R,R)-1 has been developed. This method is especially effective for the kinetic resolution of tert-butyl aryl carbinols (s = up to 23).
Facile synthesis of pivalophenones by an ultrasound assisted iodine catalysed Friedel-Crafts acylation reaction
Gopalakrishnan, Geetha,Anandhi,Narasimhan
, p. 1197 - 1198 (2007/10/03)
The use of ultrasound in the acylation reactions of various aromatics and heterocyclics with pivaloyl chloride in the presence of catalytic amount of iodine, without any added solvent and at room temperature, gives excellent yields of the respective pivalophenones in a short reaction time.
