Abstract
Methyl and methoxy substituted nitroarenes were reacted with acethophenone in the presence of sodium ethoxide in ethanol giving arylamino-conjugated diketo derivatives. A case of ipso-substitution of a methoxy group is discussed. The title compound C23H19NO2 (Mr=341.4) crystallizes in the monoclinic system, space group P21/n with a=21.579(4), b=8.526(2), c=9.983(2) Å;β=92.3(1)°;V=1835.2(7) Å3, Z=4, Dc=1.24 g cm-3, μ(Cu-Kα)=5.9 cm-1, θ{symbol}=1.5418 Å, F(000)=720. The molecule adopts the E configuration with the C=O carbonyl groups trans with respect to the ethylenic double bond.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
