Abstract

The new compound tetrakis(phenylmethoxy)methane (also known as benzyl orthocarbonate) has been produced by the action of the sodium salt of benzyl alcohol on trichloronitromethane (chloropicrin), resulting in a white crystalline solid with a melting range of 68–70 °C. The crystal structure has been determined at 153(5) K: triclinic, [Formula: see text], a = 10.161(4) Å, b = 12.664(4) Å, c = 20.472(5) Å, α = 71.78(2)°, β = 82.30(3)°, γ = 71.92(2)°. The results show the symmetry at each central carbon to be approximately S4, with average C—O bond lengths of 1.397(4) Å, O—C—O angles ranging between 113–114° and 107–108°, and C—O—C angles of 115(1)°. Additional evidence for this structure is given by nuclear magnetic resonance, infrared and mass spectra. Keywords: benzyl orthocarbonate, orthocarbonate, tetrakis(phenylmethoxy)methane.
