%X Four new fluorinated monothio-&#946;-diketones of general formula RC(SH)=CH- COCF3 have been prepared; they are: l,l,l-trifluoro-4-mercapto-4-(4-methylphenyl)but-3-en-2-one (R = p-methylphenyl), 1,1,1-trifluoro-4-mercapto-4- (4-methoxyphenyl)but-3-en-2-one (R = p-methoxyphenyl), 4-(4-bromophenyl)-l,l,l- trifluoro-4-mercaptobut-3-en-2-one (R = p-bromophenyl), and l,l,l-trifluoro-4- (2-furyl)-4-mercaptobut-3-en-2-one (R = 2-furyl). Their nickel complexes, which are brown and diamagnetic, yield stable high-spin bis-pyridine adducts. When R = p-MeC6H4, p-MeOC6H4, or p-BrC6H4 the ligand yields both copper(1) and copper(11) complexes but when R = 2-furyl only a copper(11) complex is obtained. Infrared data indicate that in the copper(1) complexes the ligand is coordinated through the sulphur atom only.
