Gramstad, Thor published the artcileHydrogen bonding. XII. Correlation of the complexing ability of organophosphorus compounds with the Taft σ* constant, Safety of Diethyltrichloromethylphosphonate, the publication is Spectrochimica Acta (1964), 20(4), 729-31, database is CAplus.
cf. CA 56, 15544b; 58, 1333a; 59, 13792b. The relation of the Taft substituent constant (Σσ*) is linear with respect to log K20°association and the shift of the OH stretching vibration fundamental (ΔvOH) for 22 organophosphorus compounds in mixed solutions with phenol, ethanol, and α-naphthol in CCl4. Σσ* is also linear with respect to log K20°association for the organophosphorus compounds with iodine in CCl4 solution, and with the wavelength shift of the visible absorption band of iodine from near 518 mμ. The relation between Σσ* and P:O stretching frequencies in cm.-1 (vPO) is not linear for these organophosphorus compounds in CCl4 solution, contrary to previous reports (Griffin, CA 55, 1415h). However, some of G.’s determinations of vPO were on pure films, and these compounds are associated in the pure state.
Spectrochimica Acta published new progress about 866-23-9. 866-23-9 belongs to chlorides-buliding-blocks, auxiliary class Aliphatic Chain, name is Diethyltrichloromethylphosphonate, and the molecular formula is C5H10Cl3O3P, Safety of Diethyltrichloromethylphosphonate.
