Kokai JP 52066531 2 Jun 1977 Showa, 9 pp. 95-84-1 is also in the experiment. (Japanese).Several reagents such as 95-84-1 is used here. (Japan). CODEN: JKXXAF. CLASS: IC: C09K003-00. APPLICATION: JP 75-142422 2 Dec 1975. DOCUMENT TYPE: Patent CA Section: 40 (Dyes, Fluorescent Whitening Agents, and Photosensitizers) Section cross-reference(s): 28 I (R = H, Cl, Me; R1 = substituted or unsubstituted benzoxazolyl or Ph group), useful as fluorescent whiteners and intermediates were prepd. For example, 2-amino-4-methylphenol [95-84-1] was treated with chloroacetyl chloride [79-04-9] to give 2-(chloromethyl)-5-methylbenzoxazole [41014-44-2] which was treated with triethyl phosphite [122-52-1] to give di-Et 5-methyl-2-benzoxazolylmethanephosphonate (II) [63842-07-9]. II was treated with nitrosobenzene [586-96-9] to give 2-(phenyliminomethyl)-5-methylbenzoxazole [63842-08-0] which was treated with II to give light greenish yellow I (R = Me, R1 = 5-methyl-2-benzoxazolyl) [1041-00-5]; 9 other I were prepd. ..

APPLICATION: JP 75-142423 2 Dec 1975. DOCUMENT TYPE: Patent CA Section: 40 (Dyes, Fluorescent Whitening Agents, and Photosensitizers) Section cross-reference(s): 28 Condensation of RCH2P(O)(OEt)2 (R1 = H, Cl, Me) proceeds smoothly at 40.degree. in the presence of Na methoxide [124-41-4] (or NaNH2) and nitrosobenzene [586-96-9] (or deriv.) in DMF, MeOH, or THF to give high yields of RCH:CHR which were used as fluorescent brighteners. For example, a soln. of di-Et 5-methyl-2-benzoxazolylmethylphosphonate [63842-07-9] in DMF was treated with a soln. from Na and MeOH and then a soln. of PhNO in DMF and stirred at 40.degree. for 1 h to give 1,2-bis(5-methyl-2-benzoxazolyl)ethene [1041-00-5]. .
