1,1,1-Trichloroacetone

1,1,1-Trichloroacetone is a chlorinated analogue of acetone with the chemical formula CH3COCCl3. It is a colourless liquid. 1,1,1-Trichloroacetone can be synthesised from chlorination of chloroacetone (1,1,3-trichloroacetone is formed as a by-product). An alternative synthesis involves the transfer of a trichloromethyl group from trichloroacetate onto acetyl chloride.
