{ALF} A simple procedure for the synthesis of methyl ketones involves alkylation at the 3-position with an alkyl halide using K2CO3 in EtOH, with in situ acetyl cleavage: Org. Synth. Coll., 5, 767 (1973). Knoevenagel condensation with aldehydes in THF in the presence of K2CO3 also occurs with acetyl cleavage, providing a simple route to alkenyl ketones: Chem. Lett., 1325 (1978). With K2CO3 and TBAB, selective one-pot monoalkylation or dialkylation with different alkyl groups can be achieved: Synthesis, 688 (1989). 3-Arylation with aryl bromides takes place in the presence of Cu(I) or Cu(II) salts in DMF: Chem. Lett., 597 (1982); Org. Synth. Coll., 6, 36 (1988).

{ALF} Strong bases, e.g. NaNH2, form the dianion which reacts with electrophiles, e.g. alkyl halides, esters, acyl halides, Michael acceptors, etc., at the less-stabilized terminal carbon: J. Org. Chem., 26, 1716 (1961); Tetrahedron Lett., 357 (1970); J. Org. Chem., 39, 2289 (1974); Org. Synth. Coll., 5, 848 (1973). For arylation at the 1-position, see Diphenyliodonium chloride, A15149. For reviews of dimetallation, see: Org. React., 17, 155 (1969); Synthesis, 509 (1977).
