Phenylmagnesium bromide 3- trifluoromethyl

Trifluorovinylmagncsium iodide couples with chloro(diethoxy)phosphanc to give the trifluoro-vinylphosphane 32 in moderate yield and phenylbis(trifluoromethyl)phosphane (34) can be obtained by reacting chlorbis(trifluoromethyl)phosphanc (33) with phenylmagnesium bromide. ... 

The carbonyl group of 3-thietanone reacts typically with nucleophiles such as hydrazine (to give 364), 2,4-dinitrophenylhydrazine, ° tosylhydrazine, semicarbazide, and phenylmagnesium bromide.It undergoes the Wittig reaction (e.g., the formation of 365) yields vary from 14 to 74%. Sodium hydroxide cleaves the presumed 2,2-bis-trifluoromethyl-4,4-diphenyl-3-thietanone to diphenylacetic acid. ... 

Preparation by adding phenylmagnesium bromide to 2-methoxy-5-(trifluoromethyl)benzonitrile,followed by hydrolysis of the intermediate imino compound formed, then demethylation of 2-methoxy-5-(trifluoromethyl)-benzophenone so obtained [568]. - Preparation by demethylation of 2-methoxy-5-(trifluoromethyl)benzophenone with boron trichloride in methylene chloride at -60° for 1 h, then at r.t. [569].
