The rate retarding effect of alkyl groups on arene metalation quantified
Baston, Eckhard,Wang, Qian,Schlosser, Manfred
, p. 667 - 670 (2000)
Metalation/trapping sequences applied to relatively inert, tert-alkyl substituted arenes tend to give poor yields unless the reagent is used in high concentrations. Under optimized conditions, even 1,4-bis(tert- butyl)benzene, 1,1,3,3-tetramethylindane an
Efficient chemoselective carboxylation of aromatics to arylcarboxylic acids with a superelectrophilically activated carbon dioxide-Al2Cl6/Al system
Olah, George A.,Toeroek, Bela,Joschek, Jens P.,Bucsi, Imre,Esteves, Pierre M.,Rasul, Golam,Prakash, G. K. Surya
, p. 11379 - 11391 (2007/10/03)
Aromatic carboxylic acids are obtained in good to excellent yield essentially free of diaryl ketones by carboxylation of aromatics with a carbon dioxide-Al2Cl6/Al system at moderate temperatures (20-80°C). To optimize reaction condit
Dimetalation: The acidity of monometalated arenes towards superbasic reagents
Baston, Eckhard,Maggi, Raimondo,Friedrich, Kirstin,Schlosser, Manfred
, p. 3985 - 3989 (2007/10/03)
Twofold hydrogen/metal interconversions ("dimetalations") can be accomplished with "spiny" arenes (tert-butylbenzene, 1,4-di-tert-butylbenzene, 1,1,3,3-tetramethylindane and congeners) and N,N-crowded anilines (2,2,6,6-tetramethyl-1-phenylpiperidine and N
