| titleOfInvention | Benzyloxy-2-nitro-ª-(1-(1-nitroalkyl))-benzyl alcohols |
| abstract | The invention comprises benzyloxy-2-nitro-a -[1-(1-nitroalkyl)]benzyl alcohols of the formula <FORM:0728013/IV (b)/1> in which X is phenyl, halophenyl, lower alkoxyphenyl or lower alkylphenyl, Y is hydrogen, phenyl, halophenyl, lower alkoxyphenyl or lower alkylphenyl, and R is hydrogen or lower alkyl, the word "lower" meaning having 1 to 8 carbon atoms. The compounds are prepared by condensing a benzyloxy-2-nitrobenzaldehyde with a 1-nitroalkane in the presence of an alkali-metal hydroxide, and acidifying the salt thus produced. The condensation may be carried out in the cold in the presence of an organic solvent such as an alkanol. In examples, (1) and (2) 5-benzyloxy-2-nitrobenzaldehyde is condensed with nitromethane in the presence of aqueous-alcoholic potassium hydroxide to give 5-benzyloxy-2-nitro-a -nitromethylbenzyl alcohol; (3) 5-benzyloxy-2-nitrobenzaldehyde is similarly condensed with 1-nitroethane to give 5-benzyloxy-2-nitro-a -[1-(1-nitroethyl)] benzyl alcohol; (4) 5-benzhydryloxy)-2-nitrobenzaldehyde is reacted with nitromethane to give 5-benzhydryloxy-2-nitro-a -nitromethylbenzyl alcohol; (5) 5-(p,p1-dimethylbenzhydryloxy) - 2 - nitrobenzaldehyde is reacted with nitromethane to give 5-(p,p1-dimethylbenzhydryloxy) - 2 - nitro - a - nitromethylbenzyl alcohol; (6) 5-(p,p1-dimethoxybenzhydryloxy) - 2 - nitrobenzaldehyde is reacted with nitromethane to yield 5-(p,p1-dimethoxybenzhydryloxy) - 2 - nitro - a - nitromethylbenzyl alcohol; (7) 5-(p,p1-dichlorobenzhydryloxy) - 2 - nitrobenzaldehyde is condensed with nitromethane to yield 5-(p,p1-dichlorobenzhydryloxy) - 2 - nitro - a - nitromethylbenzyl alcohol; (8) 4 - benzyloxy - 2-nitro-benzaldehyde is condensed with nitromethane to give 4-benzyloxy-2-nitro-a -nitromethylbenzyl alcohol; and (9) 6-benzyloxy-2-nitrobenzaldehyde is condensed with nitromethane to give 6-benzyloxy-2-nitro-a -nitromethylbenzyl alcohol. Many other analogous products of the invention are specified. Benzyloxy - b ,2 - dinitrostyrenes are prepared by dehydration of the benzyloxy-2-nitro-a -[1-(1-nitroalkyl)] benzyl alcohols. |
