The Thorpe-Ingold Hypothesis of Valency Deviation. Intramolecular Hydrogen Bonding in 2-Substituted Propane-1,3-diols1,2

“…Chem. Soc., 81, 2756(1959; H. Krieger, Suomen Ktmi., B31, B48 (1958). accord with the Thorpe-Ingold hypothesis and with the assumption that 2-substituents will not alter the geometry of propane-1,3-diol except for the C-C-C angle.…”

“…When the mixture was processed by procedure B, 3.1 g. (13.8% based on chloroacetic acid) of mixed dibenzofuranacetic acids, m.p. 115-145°, was obtained.…”
