ruthenium catalyzed hydroarylation of anilides with alkynes an efficient route to ortho alkenylated anilines
ChemInform, 2014Co-Authors: Rajendran Manikandan, Masilamani JeganmohanAbstract:Acetanilides react with symmetrical and unsymmetrical alkynes in the presence of a Ru/Ag catalytic system in a regio- and stereoselective manner providing ortho-alkenylated Acetanilides.
-
ruthenium catalyzed ortho arylation of Acetanilides with aromatic boronic acids an easy route to prepare phenanthridines and carbazoles
ChemInform, 2014Co-Authors: Ravi Kiran Chinnagolla, Masilamani JeganmohanAbstract:A wide range of ortho-arylated Acetanilides is prepared tolerating various functional groups.
-
ruthenium catalyzed oxidative ortho benzoxylation of Acetanilides with aromatic acids
ChemInform, 2014Co-Authors: Kishor Padala, Masilamani JeganmohanAbstract:The reaction of substituted Acetanilides with aromatic acids proceeds in most cases regioselectively to afford 2-benzoxylated Acetanilides.

ruthenium catalyzed ortho arylation of Acetanilides with aromatic boronic acids an easy route to prepare phenanthridines and carbazoles
Chemical Communications, 2014Co-Authors: Ravi Kiran Chinnagolla, Masilamani JeganmohanAbstract:The highly regioselective ortho-arylation of Acetanilides with aromatic boronic acids in the presence of a Ru(II) complex (3 mol%), AgSbF6 (12 mol%), Cu(OTf)2 (20 mol%) and Ag2O (1.0 eq.) is described. Later, ortho-arylated Acetanilides were converted into phenanthridine and carbazole derivatives by using Ph3PO and Tf2O or palladium or Cu(OTf)2 catalysts.

ruthenium catalyzed hydroarylation of anilides with alkynes an efficient route to ortho alkenylated anilines
Organic Letters, 2014Co-Authors: Rajendran Manikandan, Masilamani JeganmohanAbstract:Acetanilides reacted with symmetrical as well as unsymmetrical alkynes in the presence of [{RuCl2(p-cymene)}2], pivalic acid, and AgSbF6 in iso-PrOH providing ortho-alkenylated Acetanilides in a highly regio- and stereoselective manner. Later, ortho-alkenylated Acetanilides were converted into ortho-alkenylated anilines in the presence of HCl.

palladium catalyzed ortho halogenations of Acetanilides with n halosuccinimides via direct sp2 c h bond activation in ball mills
Beilstein Journal of Organic Chemistry, 2018Co-Authors: Hui Xu, Guanwu WangAbstract:: A solvent-free palladium-catalyzed ortho-iodination of Acetanilides using N-iodosuccinimide as the iodine source has been developed under ball-milling conditions. This present method avoids the use of hazardous organic solvents, high reaction temperature, and long reaction time and provides a highly efficient methodology to realize the regioselective functionalization of Acetanilides in yields up to 94% in a ball mill. Furthermore, the current methodology can be extended to the synthesis of ortho-brominated and ortho-chlorinated products in good yields by using the corresponding N-halosuccinimides.
