2-acetyl-4-methylphenyl

Similar rules apply for compounds 10-13, which contain rings. Compounds 10 and 11 are isomeric keto nitriles, and both must be named as nitriles according to Table A.2. Substance 10 is named as a benzonitri e since the -CN functional group is a substituent on the aromatic ring, but substance 11 is named as an acetonitrile since the -CN functional group is part of an open chain. The correct names are 2-acety -4-methylbenzonitrile (10) and (2-acetyl-4-methylphenyl)acetonitrile (11). Compounds 12 and 13 are both keto acids and must be named as acids. The correct names are 3-(2-oxocyclohexyl)propanoic acid (12) and 2- 3-oxopropyl)cyclohexane carboxylic acid (13).

Reaction of 2-cyanomethylpyridine with iV-(l-aryl-l-chloro-2,2,2-trifluoroethyl)-iV -(4-methylphenyl)carbodiimides, and with (1,1,2,2,2-pentachloro- and l,l-dichloro-2,2,2-trifluoroethyl)isocyanates or A-methoxycarbonyl-l,2,2,2-tetrachloro-, — l-chloro-2,2-trifluoroacetaldehyde imines afforded 3-aryl-4-cyano-l-(4-methylphenyl)imino-3-trifluoromethyl-2,3-dihydro-17/-pyrido[l,2-f]pyrimidines and 4-cyano-3-trichloro-, 4-cyano-3-trifluoro-17/-pyrido[l,2-4pyrimidin-l-ones, respectively <2004CHE47>. Refluxing 2-cyanomethylpyridine and iV-(l-aryl-l-chloro-2,2,2-trifluoroethyl)isocyanates in benzene furnished l-aryl-4-cyano-l-trifluoromethyl-l,2-dihydro-3//-pyrido[l,2-4pyrimidin-3-ones. However, when the solution of the isocyanate was added dropwise to the solution of 2-cyanomethylpyridine, and the reaction mixture was then treated with NEt at room temperature, the isomeric 3-aryl-4-cyano-3-trifluoromethyl-2,3-dihydro-l//-pyr-ido[l,2-dpyrimidin-l-ones were obtained. Reaction of l-(acetyl- and benzoylmethylene)-6,7-dimethoxy-l,2,3,4-tetra-hydroisoquinolines with PhCONCS yielded 1-acetyl-, 1 -benzoyl-9,10-dime thoxy-3-pheny 1-6,7-dihydro-2//-pyrimido[6,l- ]isoquinoline-2-thiones <2003SL2369>. 

When Cl and MeO substituents are attached to the phenolic ring, the PFR may result in displacement of those substituents by the acyl moiety. An example of chlorine displacement has been given in Section I, whereas Scheme 10 shows the case of 2-methoxy-4-methylphenyl benzoate (26), where the reaction mixture contains 2-hydroxy-5-methylbenzophenone (27), a product of methoxy substim-tion [37]. Hageman also reported the substitution of MeO by acetyl in the photolysis of 4-methoxyphenyl acetate and related esters [32]. 

The fate of the free acyl radical 68 and radical 74 is not known. Most probably it is a constituent of polymer deposits on the wall of the irradiation vessel which hitherto have not been identified more definitely.29 Moreover, the identification of methane and carbon monoxide among the gaseous products of the photolysis of 4-methylphenyl acetate (55) provides evidence for the existence of the acetyl fragment. This intermediate is expected to decarbonylate to give carbon monoxide and a methyl radical, which in turn abstracts hydrogen from the solvent.34...

When a mixture of tris(4-methylphenyl)bismuthine (2 g, 4.1 mmol), acetyl chloride (0.5 g, 6.4 mmol) and carbon tetrachloride was heated for 4 h on a water bath, the corresponding diaryl-chlorobismuthine was obtained as a white solid (1.4 g), which was recrystallized from cold dry chloroform-light petroleum, m.p. 180°C. The mother liquors and washings were united and heated for 5 h to afford chlorobis(4-methylphenyl)bismuthine as yellowish crystals, m.p. 206°C [22JCS(121)104]. 

The synthesis of 2(2-hydroxy-5-methy lphenyl)2H-4 -vinyl-benzo-triazole was accomplished (31) by a sequence of reactions similar to those which gave 2H5V. The starting material for this synthesis was, however, not o-nitroaniline but 4-ethyl-o-nitroaniline. After diazo-tiation, the diazonium compounds were allowed to react with p-cresol the condensation product gave 2(2-hydroxy-5-methylphenyl)2H-4-ethyl-benzotriazole after reductive cyclization. This compound was acetyl-ated, brominated, dehydrobrominated, and hydrolyzed to 2(2-hydroxy-5-methylphenyl)2H-4 —viny1-benzotriazole.
