β-DIKETONE INTERACTIONS Part 4. The structures and properties of 1,3-diphenyl-2-methylpropane-1,3-dione, C16H14O2, and 1,3-diphenyl-2-(4-methoxyphenyl)propane-1,3-dione, C22H18O3

The X-ray crystal structures of 1,3-diphenyl-2-methylpropane-1,3-dione and 1,3-diphenyl-2-(4-methoxyphenyl)propane-1,3-dione show them both to adopt cis-diketo (Z,Z) conformations with carbonyl-carbonyl dihedral angles of 89.0(3)deg (2-methyl derivative), and 85.5(4)deg and 77.7(4)deg for the two molecules in the asymmetric unit of the 2-(4-methoxyphenyl) derivative.These are the first acyclic β-diketones with an α-hydrogen to be reported which do not have an enol configuration in the solid state.

β-Keto enol ethers have been synthesized in very good yield in solvent-free conditions from differently substituted alcohols and β-diketones in the presence of Yb(OTf)3 as catalyst. The method is applicable to both cyclic and acyclic β-diketones with only slight differences in the experimental procedure.
