We review here new developments in decreasing the catalyst loadings in palladium-catalyzed C-C bond-formation reactions to mol ppm or mol ppb levels. This decreases the cost of the catalyst and the toxicity of the reaction system, making the reaction more attractive to industry. The Heck ...
Question: ppm and ppb are: A) toxic chemicals. B) chlorinated hydrocarbons. C) wastewater treatment strategies. D) types of polymer E) none of the above Parts-per Notation: In scientific calculations, certain values are expressed as parts-pe...
