Yield	Reaction Conditions	Operation in experiment
	In water;	b) 4.5 g of <strong>[52924-54-6]2,3-dihydroxy-5-nitrobenzaldehyde</strong> are suspended in 75 ml of water. After treatment with 4.2 g of hydroxylamine o-sulphonic acid, the mixture is stirred at 65 for 16 hours. After cooling the separated crystals are filtered under suction and washed with water. The filtrate is extracted with ethyl acetate. The crystals and the dried organic phase are combined, whereupon the mixture is evaporated and the residue is recrystallized from diisopropyl ether. There is obtained 2,3-dihydroxy-5-nitrobenzonitrile in the form of yellow crystals of m.p. 186-188.

Yield	Reaction Conditions	Operation in experiment
	In acetic acid; ethyl acetate;	a) 10.0 g of 2,3-dimethoxy-5-nitrobenzaldehyde are treated with 50 ml of glacial acetic acid and 50 ml of constant-boiling hydrobromic acid and held at the reflux temperature for 7 hours. After treatment with ice the separated precipitate is filtered under suction, washed with water and taken up in ethyl acetate. The organic phase is dried over sodium sulfate and evaporated. The crude product obtained is filtered over silica gel with ethyl acetate. After crystallization from ethyl acetate/hexane there is obtained 2,3-dihydroxy-5-nitro- benzaldehyde in the form of brownish crystals of m.p. 226-228.

(R,E)-3-((2'-(diphenylphosphino)-1,1'-binaphthyl-2-ylimino)methyl)-5-nitrobenzene-1,2-diol [ No CAS ]

Yield	Reaction Conditions	Operation in experiment
74%	In ethanol;Reflux;	General procedure: To a solution of (R)-(-)-2-(diphenylphosphino)-1,1'-binaphthyl-2'-amine1,2 (227 mg, 0.5 mmol) in absolute ethanol (4.0 mL) was added salicylaldehydes (0.5 mmol) or its analogues (0.5 mmol) at room temperature and the reaction mixture was stirred under reflux overnight. After cooling to room temperature, precipitates settled out, which were filtered to give the corresponding phosphine-salen type ligands and phosphine-Schiff base type ligands L1-L13 in good yields.
