Diafenthiuron: 1-tert-butyl-3-(26-diisopropyl-4-phen­oxy­phen­yl)thio­urea

摘要

The title compound, C23H32N2OS, is a thio­urea-based insecticide. The dihedral angle between the phenyl ring and the diisopropyl benzene ring plane is 73.18 (6)°, while that between the plane of the thio­urea group and the diisopropyl benzene ring is 86.00 (5)°. Disorder was modelled for the S atom and the two methyl C atoms of the isopropyl group over two sets of sites with an occupancy ratio of 0.742 (4):0.258 (4). In the crystal, N—H⋯S hydrogen bonds link adjacent mol­ecules, forming R 2 ²(8) inversion dimers that pack into chains along the b-axis direction.
