substituted methylenecycloalkanes. Methyl groups in the 2-position are transformed into angular methyl groups in decalin or indane derivatives. The chloromethylaluminum alkoxides produced in these reactions, i.e. 3 and 7, undergo an Oppenaueroxidation in situ in the presence of excess acrolein to give the corresponding ketone in good yield. Using these procedures, indenone 8a has been prepared from

The deoxygenation of the α,β-unsaturated ketones (1) and (5) under the Clemmensen condition yielded the olefins (2) and (6) along with their respective dimers (3+4) and (8+9). The α , β-unsaturated ketone (13) under similar treatment yielded the olefin (14) in satisfactory yield but the dimer could not be characterized. The deoxygenation of the α,β-unsaturated ketones (10) and (16) under similar con-
