A Synthesis of Diphenylmethyl Ketones
Bunce, Richard A.,Dowdy, Eric D.
, p. 3007 - 3014 (2007/10/02)
The anion derived from diphenylmethane (2 eq.) reacts with carboxylic esters and anhydrides (1 eq.) to form diphenylmethyl ketones in 55-75percent purified yields.The procedure is one-step and permits the introduction of functionality incompatible with conditions used in earlier syntheses.
