Crystal structures of 1-(4-chlorophenyl)-2-(diphenylphosphoryl)ethan-1-one and 1-(diphenylphosphoryl)-3,3-dimethylbutan-2-one

Abstract

The title compounds were synthesized via an Arbuzov reaction between an α-bromo­ketone and isopropoxydi­phenyl­phosphane. In the crystals of both compounds, mol­ecules are linked via bifurcated C—H⋯(O,O) hydrogen bonds, forming chains propagating along [100] and along [010].

Three derivatives of phenacyldiphenylphosphine oxide: influence of aromatic and alkyl substituents on the luminescence sensitization of four Ln(NO3)3 salts

“…Compounds 1-4 were characterized by 1 H, 13 C, 31 P NMR, IR and HR-MS. The crystal structures of compounds 1 and 2 have been reported, 37,38 while compounds 3 and 4 were isolated as viscous liquids.…”
