Kokai Tokkyo Koho JP 2003012614 A2 15 Jan 2003, 6 pp. (Japanese). (Japan). CODEN: JKXXAF.In this article, certain chemicals are used. Some of their cas registry numbers are 64755-43-7 and 120-95-6 CLASS: ICM: C07C213-02. ICS: C07C217-16; C07C217-18; C07C253-30; C07C253-34; C07C255-37; C07B061-00. APPLICATION: JP 2001-205366 5 Jul 2001. DOCUMENT TYPE: Patent CA Section: 23 (Aliphatic Compounds) Section cross-reference(s): 45 The phenoxypropylamines with general formula of R1R2PhO(CH2)3NH2 [wherein R1 and R2 = independently H or alkyl] are prepd. by addn. reaction of phenols and acrylonitrile, followed by hydrogenation reaction. For example, 2,4-di-tert-amylphenol was treated with acrylonitrile in H2O in the presence of NaOH to afford 3-(2,4-di-tert-amylphenoxy)propanenitrile. The above compd. was hydrogenated with H2 in MePh in the presence of Raney cobalt to give 3-(2,4-di-tert-amylphenoxy)propylamine in 98% purity. The phenoxypropylamines are useful as coupler of color films (no data). .

Study of some novel metal-chelated and brominated phthalocyanine dyes in relation to their photo-physical properties

Study of some novel metal-chelated and brominated phthalocyanine dyes in relation to their photo-physical properties. Gan, Changsheng; Yan, Tiantang; Peng, Bixian (Sch. Chem. Mater. Sci., Univ. Sci. Technology of China, Hefei 230026, Peop. Rep. China). Huaxue Wuli Xuebao, 16(4), 293-298 (Chinese) 2003 Kexue Chubanshe. CODEN: HWXUE4. ISSN: 1003-7713. DOCUMENT TYPE: Journal CA Section: 73 (Optical, Electron, and Mass Spectroscopy and Other Related Properties) Section cross-reference(s): 41, 78 Several kinds of novel tetra-substituted metal phthalocyanines have been synthesized, based on the precursor of 3-(2,4-ditert-pentylphenoxy)phthalonitrile. The central metals include lead, zinc, copper, nickel, manganese, cobalt and magnesium. These compds. are characterized by elemental anal., UV-Vis, IR and 1H-NMR. Some of them are selected to be further subjected to bromination. Through expts., we draw the conclusion that metalation of these phthalocyanines can influence their absorption wavelengths greatly. Most of the metal phthalocyanines are blue-shifted compared to that of free phthalocyanine. The film photo-absorption behavior is also investigated by spin-coating with Bu ether and the results show that there is a slight increase of absorption wavelength and the broadening of absorption bands. Under proper conditions, reacting some of these dyes with bromine can produce to a certain extent, bathochromic effect. The absorption wavelength of some of the brominated compds. 652155-13-0 and 120-95-6 which are cas registry numbers of substances are two of reagents here. is very close to that of laser used in the information technol. An attempt is made to correlate the structures of the metal-centered and brominated at-(2,4-ditert- pentylphenoxy) phthalocyanines with their photo-phys. properties. The nature of the effects of the substitution, central metals and bromination on Q-band absorption of these dyes are presented and discussed. .
