Diphenyl- -anilid

The spectra and halochromism of thiophene analogs of triphenyl and diphenyl carbinol, " the spectra of anilides of 2- and 3-thenoyl-acetic acid, " and the fluorescence of some thiophene compounds have been investigated. 

Typical operating conditions by GC and HPLC are listed in Tables 2 and 3, respectively. Anilides are separated using a weakly polar liquid-phase capillary column, such as SPB-1 or HP-5, which is prepared based on 5% diphenyl-95% dimethylpolysilox-ane for GC. For HPLC, ODS columns are used.

Neither the anilide of cinnamic acid94 nor the diphenyl substituted acroyl anilide 138 95 yields any product of rearrangement or cyclodimerization. Upon irradiation of 138 in benzene solution in a Pyrex reactor, only the isomeric /9-lactams 139 (2.3%) and 140 (37%), in addition to dihydrocarbostyril 141 (5%), were isolated. The latter is the major product upon irradiation of alkyl substituted acroyl anilides.96 On the other hand, the closely related phenyl cinnamate rearranges regularly to the ortho- and para-positions97 and does not dimerize as the other alkyl esters of cinnamic acid.98... 

A number of related reactions are worthy of mention. Benzanilide (334) is converted into phenanthridone (335) by irradiation in benzene in the presence of iodine.362 Cyclodehydrogenation is also observed in the anilides of indole-2-carboxylic acid and indole-3-carboxylic acid on irradiation in acetone.363 Irradiation of diphenyl-amine304 and certain of its JV-substituted derivatives365 yields the corresponding carbazole. The mechanism of this reaction differs from... 

Azetidinones are also formed on photolysis of cis-a-phenyl-cinnamanilide (361), but in addition a small quantity of a cis-trans mixture of 3,4-diphenyl-3,4-dihydroquinolin-2-one (362) was obtained. The yield of quinolinone was considerably increased in the photocyclization of alkyl-substituted acrylanilides.389 The anilide (363) of tiglic acid, for example, was converted into the anilide (364) of angelic acid by photochemical cis-trans isomerism, and into a mixture of cis- and [Pg.103]

The H202-HF-SbF5 system has been applied by Jacquesy and co-workers in the hydroxylation of a variety of functionalized arenes.624 Hydroxylation of phenyl esters has been shown to afford themeta and para isomers as main products625 [Eq. (5.217)]. Substantial amounts of the deacylated derivatives were obtained in the reaction of phenyl formate and diphenyl carbonate. In the hydroxylation of 2-chlorophenyl and 4-chlorophenyl acetate, regioselectivity is controlled by the chlorine substituent with the hydroxyl entering into the meta position to the ester group.626 A similar effect was observed in the hydroxylation of anilines and anilides. 

Most other reported catalytic systems rely on the use of strong nucleophiles such as 1,3-diphenyl urea (DPU), diazabicyclo[5.4.0]undec-7-ene (DBU) [37], diphenyl carbodiimide (DPC) [38] and anilides [39] to activate 0O2 and acidic substrates. 

Nitrations of phenyl derivatives of small ring heterocycles have been little studied. The nitration of 3-(4-nitrophenyI)-l-phenyl-2,2-dichloroaziri-dine (90) using potassium nitrate in sulfuric and acetic acids yields 1,3-bis(4-nitrophenyl)-2,2-dichloroaziridine and 3-(4-nitrophenyl)-l-(2-nitro-phenyl)-2,2-dichloroaziridine in 65 35 ratio. Under the same conditions the diphenyl derivative undergoes cleavage of the aziridine ring to give a mixture of nitrated anilides.
