Usage

General Description

4,4'-BIS(TRIFLUOROMETHYL)DIPHENYLMETHANE, also known as Bis(trifluoromethyl)diphenylmethane, is a chemical compound with the molecular formula C15H10F6. It is a colorless, crystalline solid that is insoluble in water but soluble in organic solvents. 4,4'-BIS(TRIFLUOROMETHYL)DIPHENYLMETHANE is used in the production of polymers, resins, and plastics as a heat stabilizer and flame retardant. It is also used as an intermediate in the synthesis of pharmaceuticals and agrochemicals. 4,4'-BIS(TRIFLUOROMETHYL)DIPHENYLMETHANE is a highly stable compound with low reactivity and low acute toxicity, but it may have adverse effects on the environment if released in large quantities.

Carbon-13 Nuclear Magnetic Resonance Studies of Carbocations. 10. Variation of Cationic Carbon Chemical Shifts with Increasing Electron Demand in 1,1-Diaryl-1-methyl (Benzhydryl) Carbocations

A series of 28 1-X-phenyl-1-Z-phenyl-1-methyl (benzhydryl) carbocations, where the X and Z substituents have been varied over the range of electron demand (3,4-CH2CH2O, 11; 4-OCH3, 12; 4-CH3, 13; 4-F, 14; 4-H, 1; 4-CF3, 15; 3,5-(CF3)2, 16), have been prepared from the corresponding alcohols by ionization in superacids and their 13C NMR spectra recorded at low temperatures (-70 to -10 deg C).Plots of the substituent chemical shifts of the cationic carbons (ΔδC+) at -70 deg C against ?C+ are linear for the electron donors (Z = 3,4-CH2CH2O to Z = H) of 13 - 16 and 1 but deviate upward from this correlation line (relative shielding) for the electron acceptors (Z = H to Z = 3,5-(CF3)2).The plots of the highly stabilized cations 11 and 12 approximate shallow curves where groups more electron demanding than 4-CH3 cause relative shielding of the cationic carbon.All these plots are interpreted in terms of competing resonance and localized inductive ?-polarization effects.
