Complexes of 3-mercapto-1,3-diphenylprop-2-en-1-one, PhC(SH)=CHCOPh, with iron(III), cobalt(III), rhodium(III), nickel(II), palladium(II), platinum(II), copper(II), silver(I), zinc(II), cadmium(II), and mercury(II) have been prepared and characterized. Complexes of 4- mercaptopent-3-en-2-one, MeC(SH)=CHCOMe, with cobalt(III) and cadmium(II) and of ethyl thioacetoacetate, MeC(SH)=CHCOOEt, with cobalt(III) and copper(I) are also reported. The infrared spectra of the complexes of 3-mercapto-1,3- diphenylprop-2-en-1-one are discussed. The similarity of the spectra of the silver(I), cadmium(II), and mercury(II) complexes to those of the free ligand and its S-methyl derivative, PhC(SMe)=CHCOPh, indicate that in these three complexes the carbonyl oxygen of the ligand is not, or is at most weakly, coordinated to the metal ion. The assignments of the principal bands in the other metal complexes of this ligand are: 1550- 1525 cm-1, v(C-C); 1480-1458 cm-1, v(C=O); 1438-1412 cm-1, v(C=O)+δ(C-H); 1270-1260 cm-1, v(C--S); 498-437 cm-1, v(M-O); 399-376 cm-1, v(M-S).

Aryl hydroxamic acid derivatives fragment in a diagnostic manner upon electron impact. A hydroxamic acid containing both styryl and benzyl substituents undergoes skeletal-rearrangement of the type ABC → AC+B. The mass spectra of the O- and N-acetyl derivatives of O- benzylhydroxamic acids are indistinguishable. M-CO2 fragments are again observed in the mass spectra of several substituted phthalimides.
