The 2,4-dinitrophenylhydrazone of patulin and other mono-2,4-dinitrophenylhydra-zones form red zones, 2-s c-butyl-4-amino-6-nitrophenol appears as a red-orange zone while dinitrophenols and their esters are colored yellow [14]. A whole range of organophosphorus pesticides do not give any reaction [12]. 

Nitrophenols are phytotoxic, and dinoseb (6-iec-butyl-2,4-dinitrophenol) has been used as a herbicide, while nitrophenols have been detected in rainwater and plausible mechanisms for their abiotic formation have been proposed (Kohler and Heeb 2003 Vione et al. 2005). The pathway for the degradation of phenols with a single nitro group depends on the position of the substituents, while...

A mixture of 28 g. (0.2 mole) of o-nitrophenol (Note 1), 30 g. (0.22 mole) of M-butyl bromide, 28 g. (0.2 mole) of anhydrous potassium carbonate, and 200 ml. of dry acetone in a 1-1. round-bottomed flask is refluxed on a steam bath for 48 hours (Note 2). At the end of this time the acetone is distilled from the mixture, 200 ml. of water is added to the residue, and the product is extracted with two 100-ml. portions of benzene. The combined benzene extracts are washed with three 100-ml. portions of 10% sodium hydroxide, the benzene is removed by distillation at... 

A technical grade of o-nitrophenol was used the yield is no better with the pure material. In place of M-butyl bromide, a corresponding amount (36.8 g.) of the iodide can be used with no change in yield. 

Cyclopeptides.1 Cyclization of polypeptides under conditions of high dilution usually proceeds in low yield. A new method involves cyclization of co-peptide-pentafluorophenyl esters in dioxane in the presence of 4-pyrrolidinopyridine and an alcohol (ethanol or f-butyl alcohol). p-Nitrophenyl esters can also be employed, but separation of p-nitrophenol from product is more difficult than that of pen-tafluorophenol. 

Cognate preparations. Butyl 2-mtrophenyl ether (o-Butoxynitrobenzene). Place a mixture of 28 g (0.2 mol) of o-nitrophenol (Expt 6.102), 28 g (0.2 mol) of anhydrous potassium carbonate, 30g (23.5 ml, 0.22 mol) of butyl bromide and 200 ml of dry acetone in a 1-litre round-bottomed flask fitted with an efficient reflux condenser, and reflux on a steam bath for 48 hours. Distil off the acetone, add 200 ml of water and extract the product with two 100 ml portions of benzene (CAUTION). Wash the combined benzene extracts with three 90 ml portions of 10 per cent sodium hydroxide solution, remove the benzene by distillation at atmospheric pressure and distil the residue under reduced pressure. Collect the o-butoxynitrobenzene at 171-172°C/19mmHg (or at 127-129 °C/2mmHg) the yield is 30 g (77%).
