Amines in aqueous system

Fragmentation Products of Sugar in the Reaction Mixture of Sugar with Amine in Aqueous System (10)... 

The reaction with ammonia or primary amines in aqueous systems has been investigated repeatedly. Generally, two types of products are obtained during the reaction. The primary product is the ring-opened isatoic amide 42, which reacts with loss of C02, favored by a low ratio of amine, to the anthranilic acid amide (43),2 6 10,86 88 while a high ratio of amine or bulky amines leads to isatoic diamides (45), which undergo facile cyclization to the quinazoline diones 36 by heating.86,89 93 The kinetics of the reaction of IA with n-butylamine show that the rate law for formation of 43 is zero order... 

Nitrosation products of inorganic amines in aqueous systems were investigated by Fitzpatrick et al. (1984) and summarized by Williams (1988, p. 104 ff). 

Aromatic diazonium salts are generally prepared by diazotization of aromatic amines in aqueous systems with nitrous acid. In non-aqueous systems, diazotizations have been carried out with isoamyl nitrite.
