چکیده مقاله:

Recent studies conducted on some “meta-effect” photochemical reactions focused on aromatic carbonyls having a substitution on one meta position of the benzophenone (BP) and anthraquinone parent compound. In this paper, two different substitutions were introduced with one  position of the BP parent compound so as to investigate possible competition between different types of “meta-effect” photochemistry at  observed in acidic solutions containing water. The photochemical pathways of 3-hydroxymethyl-3′-fluorobenzophenone (1) and 3-fluoro-3′- methylbenzophenone (2) were xplored in several solvents including acidic water containing solutions with time-resolved each meta
spectroscopic experiments and density functional theory computations. It is observed that 1 can undergo a photoredox reaction and 2 can undergo a meta-methyl deprotonation reaction in acidic water containing solutions. Comparison of these results to those previously reported for the analogous BP derivatives that contain only one substituent at a meta position indicates the introduction of electron
