Reaction Steps
Mono-, di- or tri-phenylacetic acids were reacted with 1.5 molar equivalents of DBU to produce the corresponding toluene, diphenylmethane or triphenylmethane in yields of 80, 100 and 100% respectively. All reactions were carried out over a period of 2 to 3 hrs. using 240° C., 90° C. and 40° C., respectively, as the average reaction temperature.
