are described. W, X, Y, Z, and Q are as defined in the disclosure. Also described are the processes for the manufacture of these compounds and agriculturally suitable compositions containing these as active ingredients which are useful as herbicides for general or selective pre-emergent or post-emergent control of undesired plant species and defoliants at very low concentrations of these biologically active compounds

Irradiation in the presence of N-protected amino acids at 300 nm (Rayonet) affords fluorinated arylesters by oxygenation of the 6-position in good to excellent yields and perfect regioselectivity. Even with the most suitable method investigated (ωB97XD/TApr-cc-pVDZ), deviations of up to 5 ppm from the experimental values were observed, underlining the importance of experimental measurements.
