Solid state conformational preferences of a flexible molecular backbone derived from acetone: Dependence on electron donating/withdrawing ability of substitutions
Varughese, Sunil,Draper, Sylvia M.
, p. 2298 - 2305 (2010)
Conformational preferences, crystal packing, and intermolecular interactions can play a pivotal role in solid state reactions, and in particular for bis(phenyl)acetones, these factors are known to determine the rate of the photodecarbonylation process. In
Synthesis of acyclic ketones by catalytic, bidirectional homologation of formaldehyde with nonstabilized diazoalkanes. Application of a chiral diazomethyl(pyrrolidine) in total syntheses of erythroxylon alkaloids
Wommack, Andrew J.,Kingsbury, Jason S.

This work offers a catalytic approach to convergent ketone assembly based upon formal and tandem C-H insertion of diazoalkanes in the presence of limiting amounts of monomeric formaldehyde, which is easily generated as a gas by thermolysis of the inexpensive and abundant paraformaldehyde (～30 USD/kg). The method forms di-, tri-, and even tetrasubstituted acetones with high efficiency, and it has streamlined a synthesis of (-)-dihydrocuscohygrine in which the absolute stereochemistry of a proline-based starting material is preserved. Assisted by the advent of new protocols for hydrazone oxidation, we also provide full details on handling non-carbonyl-stabilized diazo compounds.
Synthesis of poly(para-phenylene)(2-isocyano-2-tosylpropane-1,3-diyl), poly(para-phenylene)(2-oxopropane-1,3-diyl) and oligo(cyclopentadienones) via carbonylative coupling of α,α′-dibromoxylene

Poly(para-phenylene)(2-oxopropane-1,3-diyl), a potential precursor of linear graphene, is generated in low yield from hydrolysis of a previously unknown poly(para-phenylene)(2-isocyano-2-tosylpropane-1,3-diyl) generated from inexpensive, commercially available starting materials.

Dakin-West synthesis of β-aryl ketones
Tran, Khanh-Van,Bickar, David
, p. 6640 - 6643 (2007/10/03)
Triethylamine and 1-methylimidazole were found to be selective catalysts for the Dakin-West synthesis of diaryl ketones and aryl methyl ketones, respectively. In the 1-methylimidazole-catalyzed reaction, catalysis is due to the simultaneous formation of both an effective acylating agent, 1-acyl-3-methylimidazolium, and a base, carboxylate anion. Hydrocinnamic acid, a compound previously reported to be unreactive under Dakin-West conditions, forms 4-phenyl-2-butanone when the reaction is catalyzed by 1-methylimidazole.
A novel synthesis of bisbenzyl ketones by DCC induced condensation of phenylacetlc acid

1,3-Dicyclohexylcarbodiimide (DCC) has been found to effect condensation of two molecules of phenylacetic acids in the presence of dimethylaminopyridine leading to the formation of bisbenzyl ketones.
