On the Decomposition Products and Pathway of Lower Fatty Acids in Water by Ozone Treatment and UV Irradiation.

p-Xylene was oxidatively converted to terephthalic acid at room temperature with ∼98% selectivity in the absence of any catalysts via ozone treatment with concurrent UV irradiation, without the production of global warming gases.

Significant Difference

The objective of this study was to determine the effects of ozone on membrane lipids and on the electron-density patterns of cell membranes in electron micrographs. Analysis of fatty acids from tobacco leaves fumigated with ozone indicated that there was no significant difference between the ozone-treated and the control plants in the relative amounts of the fatty acids. This suggests that if the primary site of ozone action is unsaturated lipids in membranes then the amounts of affected unsaturated fatty acids are too small to be detected by gas chromatography. In support of this, characteristic electron-microscopic images of membranes are observed in cells of fumigated leaves. However, measurements of the length and width of the chloroplasts and the determination of axial ratios indicated that the ozone treatment resulted in a shrinkage of the chloroplasts. In contrast, mitochondrial changes are apparently explained in terms of ozone-induced swelling.

[Mn(CO)3(R2PCH2)3CCH3]ClO4 (1a) (R = C6H5) reacts with NaBH4 on UV irradiation to yield HMn(CO)2(R2PCH2)3CCH3 (2a). [Mn(CO)3(R2PCH2)3CCH3]BR4 (1b) gives only decomposition products. Boiling of 1a or b and NaOH in acetone/water does nots give 2a but the new hydride HMn(CO)3(R2PCH2)2C(CH3)CH2PR2 (3a). This compound cannot be prepared on ultraviolet irradiation of a solution of 1a or b and NaBH4 in methyl alcohol or acetone. The analogous deutendes DMn(CO)2(R2)PCH2)3CCH3 (2b) and DMn(CO)3(R2PCH2)2C(CH3)CH2PR2 (3b) were also prepared. The new compounds were characterized by their IR, Raman, 1H NMR and 31P NMR spectra.

Direct Attack

8-Methoxypsoralen (8-MOP) in ethanol, acetone, benzene, or CCl4 is photoxidized under UV- irradiation (320-400 nm). Photoxidized 8-MOP (O2-8-MOP) is stable in the organic solvents, but it is destructed in water or in liposome suspension. The destruction rate constants are 0.04 s-1 in water and 0.004 s-1 in liposome membranes as estimated by the kinetics of the chemiluminescence accompanying the destruction. In course of O2-8-MOP destruction the residues of phospholipid unsaturated fatty acids are oxidized. Generation of the singlet oxygen (1⊿g) by excited 8-MOP is observed neither in acetone, nor in ethanol. Quantum yield of 1⊿g formation in CCl4 is less than 3%. A pattern is proposed for 8-MOP-sensitized oxidation of unsaturated lipids proceeding without direct attack of lipids by singlet oxygen.
