| titleOfInvention | Production of spirooxazine compound |
| abstract | PURPOSE: To obtain the titled compound useful as a material for printing material, optical instruments, recording, medical decorative materials, etc., by subjecting a reaction product of an indolenium salt compound with nitrous acid to reaction with both a specific amine compound and a basic substance. n CONSTITUTION: (A) A reaction product of an indolenium salt compound expressed by formula I [R 1 represents 1W20C (substituted)alkyl, 7W20C (substituted) aralkyl or 6W9C (substituted)aryl; R 2 and R 3 represent the same as defined in R 1 or 3W10C cycloalkyl together with the 3rd position carbon atom; A ring represents (substituted)aromatic ring; X represents anionic eliminating group] with nitrous acid is reacted with both (B) a compound expressed by formula II (B ring represents the same as defined in A ring) and (C) a basic substance preferably in a molar ratio of A:B:C=1:1W50:0.5W10 to afford the aimed compound expressed by formula III. n COPYRIGHT: (C)1988,JPO&Japio |
