Benzoin, $C X_{6} H X_{5} - CH (OH) - CO - C X_{6} H X_{5}$ , is treated with one equivalent of $HIO X_{4}$ . The products are

An alpha-hydroxy ketone is cleaved between the carbinol carbon and the carbonyl carbon. The

CHOH

end gives

C X_{6} H X_{5} CHO

and the

C = O

end gives

C X_{6} H X_{5} COOH

. One mole of

HIO X_{4}

is consumed.
