3-Benzoyl-1,2,4,5-tetraphenylpentane-1.5-dione. A molecular paddlewheel

Racemic (2R,4R)-, (2S,4S)-3-benzoyl-1,2,4,5-tetraphenylpentane-1,5-dione results from the alkali-induced condensation of acetophenone with desoxybenzoin in the presence of air. The structure which resembles that of an irregular five-bladed paddlewheel is confirmed by X-ray crystallography.

An efficient simple one-pot synthesis, characterization and structural studies of some 1,2,3,5-tetraarylpentane-1,5-diones

A series of 1,2,3,5-tetraarylpentane-1,5-diones (9-23) were synthesised by simple one-pot method and characterized by FT-IR, 1H NMR, 13C NMR and mass spectral techniques. The structure of 3-(4-fluorophenyl)-1,2,5-triphenylpentane-1,5-dione (10) was determined by single crystal X-ray diffraction analysis. The compound 10 crystallize in monoclinic crystal system, in C2/c space group. The torsional angle between the two keto groups was found to be -29.50. The C(23)C(22)C(15)C(8)C(7) chain is almost planar with "W" conformation and observed maximum deviation is 0.122 ? for C(15) from the C(23)/C(22)/C(15)/C(8)/C(7) plane.

An efficient and improved synthesis of 1,5-diketones: versatile conjugate addition of nucleophiles to α,β-unsaturated enones and alkynones

Several 1,5-diketones have been prepared in good to excellent yields by versatile conjugate addition of nucleophiles such as cyclic or acyclic ketones, amines and thiols to α,β-unsaturated enones and alkynones, in the presence of catalytic amounts of 10%

Photochemical Reaction of 2,4,4,6-Tetrasubstituted 1,4-Dihydropyridines in Deaerated Media: Photocolouration and Photorearrangement accompanying Dehydrogenation

The photochemical colour change of 2,2,4,6-tetraphenyl-1,4-dihydropyridine (1) in deaerated solutions from colourless to violet, which has been reported as a photochromic phenomenon, was found to be an irreversible change and to give 2,3,4,6-tetraphenylpy
