Syntheses and X-ray structures of new phenoxy imino compounds.

Four new phenoxy imino compounds were synthesized, and the solid-state structures of 1– 3 were determined by single-crystal X-ray diffraction study, giving crystallographic data as follows. 2-Acetyl-6-[1-(2,6-diisopropylphenylimino)ethyl]-4-methylphenol ( 1): a = 13.5893(5) Å, b = 10.5781(4) Å, c = 15.6778(4) Å, β = 113.1804(18)^○, P2₁/c. 2,6-[1-(2,6-Diisopropylphenylimino)ethyl]-4-methylphenol ( 2): a = 12.1909(5) Å, b = 16.3324(6) Å, c = 15.9456(7) Å, β = 96.990(2)^○, P2₁/c. 2-Acetyl-6-[1-(4-bromine-2,6-dimethylphenylimino)ethyl]-4-methylphenol ( 3): a = 7.5337(4) Å, b = 10.0457(5) Å, c = 12.6163(4) Å, α = 90.139(3)^○, β = 104.003(3)^○, γ = 106.485(2)^○, P−1. Their molecular structures show that the 2,6-substituted phenyl ring is located approximately orthogonal to the hydroxyphenyl ring with the dihedral angle varying from 85.2^○ to 101.4^○.
