The Ethylene Ketal Protecting Group Revisited: The Synthesis of 4-Hydroxy-4, 4-Diphenyl-2-Butanone
Baar, Marsha R.; Russell, Charles E.; Wusthoiz, Kristen L.
Journal of Chemical Education, v82 n7 p1057-1058 Jul 2005
An experiment to demonstrate the use of ethylene ketal as a protecting group, one that can be completed in four lab periods, is described. The hydroxy ketone like 4-hydroxy-4, 4-diphenyl-2-butanone formed during the reaction can be identified by its melting point, IR, and (super 1)H NMR.
