Abstract

902,059. Dibenzoxazolyl - ethylene compounds. CIBA Ltd. Jan. 13. 1961 [Jan. 28. 1960], No. 1543/61. Addition to 835,894. Class 2(3). Di-benzoxazolyl-ethylene compounds of the general formula in which A is a benzene nucleus in which two adjacent carbon atoms are members of the oxazole ring and which may be substituted by chlorine or lower alkyl or low alkoxy groups, are prepared by contacting the corresponding compounds at elevated temperature with a phosphoric acid of formula H n + 2 P n O 3n + in which n>1. The process is preferably carried out at a temperature in the range 140-200‹C.
