The synthesis of cyclo-penta-, -hexa- and -hepta-[d]xanthones 5 from (E)-(2-hydroxyphenyl)-5-arylpent-4-ene-1,3-diones 4, cycloalkanones and pyrrolidine is described. Reactions to modify 5 in an attempt to synthesize analogues of the five naturally occurr

A few metal complexes of the type ML2nB [where M=Cu(II), Ni(II), Co(II) and VO(II); L=2-hydroxy-ω-(2′-furylacryloyl)-acetophenone(HFA); B=H2O; n=0,2] and Ru(II) complexes of 2-hydroxy-ω-(4-X-cinnamoyl)acetophenones (HXCA) [where X=H, Cl, Me or OMe] have been prepared and characterized by elemental analysis, IR, electronic, and ESR spectra and magnetic susceptibility studies. The ligands coordinate through carbonyl and enolic oxygens. From the ESR spectra it is observed that copper(II) and vanadyl(IV) complexes are monomers.
