2-cyanophenyl methyl

Other pertinent examples include splitting of the anion radicals from p-nitrophenyl metyl sulfone and p-cyanophenyl methyl sulfone (Pilard et al. 2001). The nitrophenyl species undergoes the preferential cleavage of the Ar-S bond, whereas the cyanophenyl species expels both CN and CH3S02 groups in the two parallel cleavage reactions. 

PET reactions of benzylic silanes with polycyano-aromatic compounds have been applied to photoresist and electron-beam resist technologies. "" The photoreaction of poly(4-trimethylsilyl-methylstyrene) in benzene-acetonitrile with DCB affords insoluble polymer via photo-cross-linking, which contains 4-cyanophenyl-methyl groups. In the case of 1,2,4,5-tetracyanobenzene, soluble 2,4,5-tricyanophenylmethyl-substituted polystyrene is produced. But,... 

Aminothiocarbonylphenyl)methoxy] derivative 384 was obtained from 8-[(4-cyanophenyl)methoxy]-2-cyclohexy 1-2,3,4,6,11,11 a-hexahydro-l/7-pyrazino[l,2-i]isoquinoline-l,4-dione by treatment with (EtO)2P(S)SH and one drop of H2O at room temperature for 17 h, then followed by addition of more H2O (98MIP7). Reaction of 8-[(4-aminothiocarbonylphe-nyl)methoxy] derivative 384 and MeCOCH2Cl yielded 8- [4-(4-methylthia-zol-2-yl)phenyl]methoxy derivative 385. 7-Bromomethyl derivative was prepared from the 8-hydroxymethyl-8-[(4-cyanophenyl)methoxy]-2-cyclo-pentyl-2,3,4,6,11,1 la-hexahydro-177-pyrazino[l, 2-i]isoquinoline-1,4-dione with PBr3 in CH2CI2 at room temperature. 7-[(l-Pyrazolyl)methyl] derivative was obtained from 7-bromomethyl derivative by treatment with pyrazole in the presence of NaH in DMF at 50 °C. 

Cyanophenyl azide is of interest in that on photolysis in methanol/tetrahydrofuran solution, an unseparated 1 1 mixture (by HNMR spectroscopy) of 2-methoxy-3//-azepine-3-carbonitrile and -7-carbonitrile (44%) is formed.197-282 Likewise, irradiation of 2-azidophenyl methyl ketone in methanol furnishes a mixture of 3-acetyl-2-methoxy- (11 %) and 7-acetyl-2-methoxy-3//-azcpine (3%) along with 3-methyl-2,l-benzisoxazole (18%).78... 

Attempts to synthesize a condensed pentazine derivative by reaction of 6-chloro-l,2,4,5-tetrazino[3,2-a]isoindole (409) with sodium azide led to the isolation of 3-methyl-6-(2-cyanophenyl)-l,2,4,5-tetrazine (412) rather than the azide (410) or its valence tautomer (411) which contains a pentazine structure (Scheme 23) (82UP22100).
