with two-equiv. of aqueoustitaniumtrichloride add to the carbonylcarbon atom of simple ketones (acetone, cyclopentanone, cyclohexanone) and aldehydes (acetaldehyde, propionaldehyde, benzaldehyde) affording subatituted pyridylglycols in very good yields. The present one-pot method has considerable advantage over the existing procedure. The reaction is discussed in terms of a radical mechanism in which
