Romanian scientists compared one-electron transfer reactions from triphenylmethyl or 2-methyl benzoyl chloride to nitrobenzene in thermal (210°C) conditions and on ultrasonic stimulation at 50°C (lancu et al. 1992, Vinatoru et al. 1994, Chivu et al. 2006). In the first step, the chloride cation-radical and the nitrobenzene anion-radicals are formed. In the thermal and acoustic variants, the reactions lead to the same set of products with one important exception The thermal reaction results in the formation of HCl, whereas ultrasonic stimulation results in CI2 evolution. At present, it is difficult to elucidate the mechanisms behind these two reactions. As an important conclusion, the sonochemical process goes through the inner-sphere electron transfer. The outer-sphere electron transfer mechanism is operative in the thermally induced process.

A reactor packed with FeCl3 supported on A1F3 was preactivated with HF. 2-(Methyl)benzoyl chloride (384 g h 2) and N2 were passed through with C12/HF for approx. 2 h. This gave a mixture (1.03 kg) containing 2-(trifluoromethyl)benzoyl fluoride (8) yield 612 g (70.4%) and a 2-(trifluoromethyl)chloro-benzoyl fluoride byproduct, the structure was not elucidated (13.4%).

The sulfinyl chirality has shown [86] considerable utility in asymmetric synthesis, particularly for carbon-carbon bond formation (see Sections 2.6.2 and 4.2.8). Its use as the chiral source in a NADH mimic has been reported [240]. Reduction of methyl benzoyl formate by enantiopure l-propyl-(S)-3-(p)-tolyl)sulfinyl-l,4-dihydropyridine yielded the (/ )-mandelate with 96% e.e.
