1-Amino-4-phenyl-2-butanethiols were synthesized and characterized and their antioxidant activity in auto-oxidation of cumene and in their reaction with cumyl peroxide radicals and cumyl hydroperoxide was studied.     

Cobalt(II) complex with 4,4,4-trifluoro-1-thienylbutane-1,3-dione and dimethyl sulfoxide: Molecular and crystal structures

The crystal structure of a cobalt(II) complex with 4,4,4-trifluoro-1-thienylbutane-1,3-dione (Tfa) and dimethyl sulfoxide (DMSO) was determined using X-ray diffraction. The crystals are monoclinic: a = 7.590(3) Å, b = 17.996(8) Å, c = 10.440(4) Å, β = 106.263(8)°, V = 1368.9(10) ų, space group P2 ₁, Z = 2, ρ_calcd = 1.595 g/cm³, R = 0.0364. The coordination polyhedron of the cobalt atom is an octahedron made up of four O atoms of two Tfa ligands and two O atoms of two DMSO molecules. The deviation of the cobalt atom from the plane of 4O(Tfa) is 0.037 Å. The average Co-O(DMSO) and Co-O(Tfa) bond lengths are 2.122 and 2.052 Å, respectively.
