Hydrogen bond association of phenol with 5,5-dimethyl-2-oxo-1,3,2-dioxaphosphorinanes and diethylphosphonates, SDS of cas: 866-23-9, the publication is Acta Chemica Scandinavica, Series B: Organic Chemistry and Biochemistry (1977), B31(5), 345-53, database is CAplus.
The association constant and enthalpy of formation of the equilibrium between phenol and twelve 5,5-dimethyl-2-oxo-1,3,2-dioxaphosphorinanes I (R = Cl, CCl3, OMe, Ph, NMe2, etc.) and six diethylphosphonates (EtO)2P(O)R1 (R1 = CCl3, SMe, CPh3, etc.) were determined The association constant, enthalpy of association, half band width, ν1/2, of the complexed O-H bond, P(O) bond moment, μPO, and excess charge d., Δq, on the phosphoryl O give linear relations with the O-H frequency shift, ΔνOH. The calculated P(O) bond moment in the axial and equatorial position gives a linear correlation with the exptl. P(O) stretching frequency. Furthermore, the square root of the addnl. dipole moment, Δμ1/2, due to H bond formation, correlates linearly with the association constant, the O-H frequency shift, and with the half band width. A close relationship between band width of the complexed O-H bond and the strength and polarity of the H bonded complex is deduced.
