“…Whereas ethylene bromide is unreactive toward liquid ammonia (276; cf. 258), 1,3-propanediamine is readily prepared by simply adding 1,3dibromopropane to liquid ammonia and allowing the latter to evaporate (37). At room temperature, 1,3-dibromopropane forms both 1,3-diaminopropane (45 to 50 per cent) and NH2(CH2)3NH(CH2)3NH2 (25 per cent).…”

Complex formation between Cu2+ and several ligands, each containing two amino and two amide groups, has been studied potentiometrically and spectrophotometrically. A digital computer was used to determine the composition of the complex species formed and to calculate their stability constants. N,N′‐diglycyl‐1, 2‐diaminoethane and its homologues form 5‐, 6‐, 7‐, 8‐ and 9‐membered rings between the two amide groups, respectively. No tendency towards formation of binuclear species has been observed.

Seven new macrocyclic di‐ and tetramides have been prepared by the cyclization reaction of various polyamines or, in one case, a dimercaptan with a bis(α‐chloroamide) or diethyl malonate. Three of the resulting macrocyclic diamides were reduced with borane to form the corresponding polyaza‐crown analogs. Macrocycles prepared include two tetraaza‐12‐crown‐4, two tetraaza‐13‐crown‐4, two tetraaza‐14‐crown‐4, one dithiadiaza‐14‐crown‐4, one tetraaza‐15‐crown‐4 with a piperazine subcyclic group, one dibenzotetraaza‐24‐crown‐8 and one octaaza‐30‐crown‐8 with two piperazine subcyclic groups.
