A solution of 100 g (1.7 mols) of isopropylamine in 60 cc of water was stirred into a solution of 4-hydroxyphenoxypropylene oxide. After the exothermic reaction has subsided, the reaction mixture was heated for two hours at 60Thereafter, the aqueous ethanol was distilled off, and the solid residue was dissolved in aqueous hydrochloric acid comprising more than the theoretical stoichiometric molar equivalent of hydrochloric acid. The aqueous acid solution was extracted with ether and was then made alkaline with sodium hydroxide, whereby a solid crystalline precipitate was formed which was filtered off and dried over phosphorus pentoxide. The product was 1,1 -(4 -hvdroxvphenoxv)-2-hvdroxv-3-isopropylamino-pro-pane. Its hydrochloride had a melting point of 166°Cto 169°C. 

Photolytlc. The dye-sensitized photodecomposition of ametryn was studied in aqueous, aerated solutions (Rejto et al, 1983). When an aqueous ametryn solution was irradiated in sunlight for several hours, 2-(methylthio)-4-(isopropylamino)-6-amino-5-triazine and 2-(methylthio)-4-(iso-propylamino)-6-acetamido-5-triazine formed in yields of 55 and 2.6%, respectively. Continued irradiation of the solution led to the formation of 2-(methylthio)-4,6-diamino-5-triazine which eventually decomposed to unidentified products (Rejto et al., 1983). The UV (7, = 253.7 nm) photolysis of ametryn in water, methanol, ethanol, n-butanol, and benzene yielded the 2-//analog 4-(ethylamino)-6-isopropylamino-5-triazine. Photodegradation was not observed at wavelengths >300 nm (Pape and Zabik, 1970). 

Photolytic. In aqueous solutions, atrazine is converted exclusively to hydroxyatrazine by UV light = 253.7 nm) (Khan and Schnitzer, 1978 Pape and Zabik, 1970) and natural sunlight (Pape and Zabik, 1972). Irradiation of atrazine in methanol, ethanol, and / -butanol afforded Atratone [2-methoxy-4-(ethylamino)-6-isopropylamino-5-triazine], 2-ethoxy-5-triazine analog, and a 2 n butoxy-s-triazine analog, respectively (Pape and Zabik, 1970). Atrazine did not photodegrade when irradiated in methanol, ethanol, or in water at wavelengths >300 nm (Pape and Zabik, 1970). Hydroxyatrazine, two de-A-alkyls and the de-A/A/ -dialkyl analogs of atrazine were produced in the presence of fulvic acid (0.01%). 

When prometryn in aqueous solution was exposed to UV light for 3 h, the herbicide was completely converted to hydroxypropazine. Irradiation of soil suspensions containing prometryn was found to be more resistant to photodecomposition. About 75% of the applied amount was converted to hydroxypropazine after 72 h of exposure (Khan, 1982). The UV (A = 253.7 nm) photolysis of prometryn in water, methanol, ethanol, /i-butanol, and benzene yielded 2-methylthio-4,6-bis(isopropylamino)-s-triazine. At wavelengths >300 nm, photodegradation was not observed (Pape and Zabik, 1970). Khan and Gamble (1983) also studied the UV irradiation (A = 253.7 nm) of prometryn in distilled water and dissolved humic substances. In distilled water, 2-hydroxy-4,6-bis(isopropylamino)-5-triazine and 4,6-bis(isopropylamino)-5-triazine formed as major products.

Methylation of diamines with formaldehyde and formic acid yields the tetramethyl derivatives, e.g., tetramethyldiaminobutane (92%). In most instances, alkylation of amino acids by this same combination gives complex products, although a-dimethylaminobutyric acid can be made from the corresponding a-amino acid in 80% yield. Reaction of the readily available amino alcohols like N-raethylethanolamine and 2-isopropylamino-ethanol gives the N,N-dialkyl derivatives. ... 

A study of the photodeconjugation reaction of the ester (136) in the presence of a variety of optically active amines such as (IR,2S)-l-phenyl-2-isopropylamino propanol has shown that the product can be obtained with an enantiomeric excess of about 70 X. Irradiation of the alkynylketones (137) in alcohols (methanol, ethanol or propanol) affords the furan derivatives (138) by a free radical hydrogen abstraction path. Excitation of the cyclohexenone derivatives (139) yields the cyclized products (140) the structures of which were verified by X-ray crystallography. The formation of the amide products is reminiscent of a Norrish Type II process.
