Reaktionen von Diphenylcarbinolen mit Phosphorsäure

Reactions of Diphenylcarbinols with Phosphoric Acid In contrast to the reaction of 1,1-diphenyl-2-methyl-2-aminopropanol-(1) (1) with phosphoric acid to 2-amino-2-(9-fluoreno)-propane (2) , no analogous reaction is observed with various 1,1-diphenylcarbinols; rearrangement and elimination reactions are found. The products of these reactions are investigated mainly by NMR- and mass spectrometry.
