supporting information, p. 4824 - 4827 (2016/10/14)
An efficient synthesis of α-acylphosphoranes by palladium-catalyzed carbonylation of aryl iodides with carbon monoxide and stabilized phosphonium ylides has been developed. Featuring 44 examples, the protocol displayed a wide substrate scope under mild reaction conditions, showcasing its potential in synthetic organic chemistry.

Wasserman, Harry H.,Baldino, Carmen M.,Coats, Steven J.
, p. 8231 - 8235 (2007/10/03)
Dimethyldioxirane (DMD) has proven to be an effective reagent for the selective conversion of phosphoranylidene intermediates 4 to the corresponding vicinal tricarbonyls 5.Unlike existing oxidation protocols which employ relatively vigorous conditions, th
The Conversion of Carboxylic Acids to Keto Phosphorane Precursors of 1,2,3-Vicinal Tricarbonyl Compounds
Wasserman, Harry H.,Ennis, David S.,Blum, Charles A.,Rotello, Vincent M.
