Web1,2-Bifuctional thiocyanodiphenylphosphinoylation of alkenes is established through the phosphinoyl radical addition followed by Cu-catalyzed thiocyanation. This one-pot … WebNov 1, 2003 · The absolute rate constants for the reaction of phosphinoyl radicals with Ph 2 I + and EMP + were determined by laser flash photolysis. Laser flash photolysis (355 nm excitation) of 4a affords a readily detectable transient absorption corresponding to the phosphinoyl radical 4c with maxima at 330 and 450 nm [42]. The transient decayed with ...
