To a solution of 4-bromo-2-fluorobenzylamine and triethylamine in chloroform was added dropwise a solution of 4-chloro-2-nitrobenzoyl chloride in chloroform at 0°C with stirring and the mixture was stirred at the same temperature for 1 h. The reaction mixture was washed in turn with diluted aqueous hydrochloric acid and water, and then dried. Evaporation of the solvent followed by recrystallization from diethyl ether gave N-(4-bromo-2-fluorobenzyl)-4-chloro-2-nitrobenzamide.

To a stirred and cooled (ice bath) suspension of 25 parts of aluminum chloride in 52 parts of fluorobenzene is added dropwise a solution of 27.5 parts of 4-chloro-3-nitrobenzoyl chloride in 52 parts of fluorobenzene. Upon completion, stirring is continued overnight at room temperature. The reaction mixture is poured onto water and the product is extracted with methylene chloride. The extract is washed successively with sodium hydrogen carbonate solution and water, dried, filtered and evaporated in vacuo. The solid residue is crystallized from 2-propanol, yielding 4-chloro-4 -fluoro-3-nitrobenzophenone MP 97.9°C. 

The use of polyphosphoric acid as a reagent for the synthesis of 2-substituted oxazolo[4,5-6]pyridines (449) has been reported (Scheme 52) (89JHC289, 90JHC1825). For example, acylating 2-chloro-3-aminopyridine (447) with m- or p-nitrobenzoyl chloride followed by heating of the intermediate (448) in polyphosphoric acid (85% phosphorus pentoxide) for 3 h at 200°C gave good yields of the oxazolopyridines (449). 

Synthesis of l,4,2-benzodiazaphosphepin-5-one 2-oxides 277 was conducted in good overall yield from 5-chloro-2-nitrobenzoyl chloride 273 and substituted (amino)methylphosphonates 274. The key step in this method is the base-induced cyclization of (2-aminobenzamido)methylphosphonates 276 to the l,4,2-benzodiazaphosphepin-5-one 2-oxides 277 <1999JOC8156>.

The acylation of 2-methyl-2-thiazoline (211) with p-nitrobenzoyl chloride or phthaloylglycyl chloride in benzene yields initially 2-chloro-iV-acyl-thiazolidines (212), which are dehydrohalogenated by triethylamine to 2-methylene-iV-acylthiazolidines (214) or converted into 2-hydroxy(or... 

Secondary nitroaUcanes are oxidized to ketones by 3-chloro- or 4-nitrobenzoyl peroxide by way of their anions thus MePhCHN02 gives acetophenone in 92% yield. The same reaction can be carried out with sodium chlorite in methylene chloride/aqueous sodium hydroxide/tetrabutylammonium hydrogen sulphate under phase-transfer conditions. Nitrones 382 (R = H or Me = Me, C02Me, CONHMe or CONMe2 R = t-Bu or Ph) are formed when the sodium salts 381 of nitroaUcanes are treated with the appropriate nitroso compounds 24 ...
