title: Efficient and green sonochemical synthesis of 3,3-bis(4-(dimethylamino)phenyl)indolin-2-ones.
abstract: A simple, green sonochemical synthesis of 3,3-bis(4-(dimethylamino)phenyl)indolin-2-ones, 2,2-bis(4-(dimethylamino)phenyl)-1H-indene-1,3(2H)-dione, 2,2-bis(4-(dimethylamino)phenyl)acenaphthylen-1(2H)-one and 5-(4-(dimethylamino)phenyl)-5-hydroxypyrimidine-2,4,6(1H,3H,5H)-triones using indium(III) chloride catalyst in aqueous media at room temperature is reported. Good yields, easy workup, short reaction time and the use of water as a solvent that is considered to be relatively environmentally benign are advantages of this new method.
