Development of a Rhodium(II)-Catalyzed Chemoselective C(sp3)-H Oxygenation

supporting information, p. 14937 - 14942 (2015/10/19)
We report the first example of RhII-catalyzed chemoselective double C(sp3)-H oxygenation, which can directly transform various toluene derivatives into highly valuable aromatic aldehydes with great chemoselectivity and practicality. The critical combination of catalyst Rh(OAc)2, oxidant Selectfluor, and solvents of TFA/TFAA promises the successful delivery of the oxidation with satisfactory yields. A possible mechanism involving a unique carbene-Rh complex is proposed, and has been supported by both experiments and theoretical calculations.
The investigation of nucleophilic reactions of 3 -bromo/chloro phthalide with amines
Desai,Chaphekar,Samant
, p. 810 - 813 (2007/10/03)
The reaction of 3-bromo/chloro phthalide 1a/b with secondary amines in polar solvents gives the corresponding amides of 2-formylbenzoic acid, while in nonpolar solvents gives 3-aminophthalides. The reaction of 1a/b with aromatic primary amines gives 3-arylaminophthalides, while with aliphatic primary amines 3-hydroxyphthalimidines are obtained.
A regioselective synthesis of dimethyl phthalide-3-phosphonates
Watanabe,Ijichi,Furukawa
, p. 94 - 98 (2007/10/02)
Dimethyl phthalide-3-phosphonates having various substituents on the benzene ring were regioselectively synthesized by the reaction of N,N-diethyl-2-formylbenzamides with tert-butyldimethylsilyl dimethyl phosphite followed by treatment with methanesulfonic acid. N,N-Diethyl-2-formylbenzamides were regioselectively prepared by ortho lithiation-formylation of the corresponding benzamides.
