Tomalia developed the polyamidoamine (PAMAM) dendrimers via the repetition of a simple two-step procedure (1)1,4-addition of a nucleophilic core (e.g. ammonia, ethylene diamine or tris(2-aminoethyl)amine) to methyl acrylate followed by amida-tion of the resulting ester with an amine functionality (e.g. ethylene diamine, propylene diamine) [188, 189] (see Fig. 18). PAMAM dendrimers could be synthesised as high as generation seven, due to the high yield of the synthetic procedure. From that point the steric considerations began to dominate, making the addition of any subsequent generations difficult [168].

Other trimerization catalysts that have been reported are amines [ 15,15a], salts of weak acids [16], potassium acetate, sodium carbonate [17], soluble compounds of K, Mg, Zn, Hg, Cu, Ni, Cr, Sn, Al, V, Ti [18], and epoxides in the presence of tertiary amines [19] such as triethylene diamine-propylene oxide [20]. Sandler [21] employed a variety of catalysts including calcium naphthenate, amines, and organometallics.

Both ethylene and propylene oxide have been used in the preparation of adducts from a variety of amines, including ethylene diamine and diethylene triamine. The latter amine provides adducts which appetu" free of skin sensitising effects. 

Bases function in a more complex way than simply by acting as a halogen acceptor, for they cannot always be used interchangeably, and the product may depend on the base used (58,68,69). Diamines, such as ethylene-, propylene-, or hexamethylene diamines may function differently than monoamines. Diamines were thought to function through chelate formation (32). Loven and Speckamp (40) concluded that selectivity in reduction of a...

The immobilization of metal catalysts onto sohd supports has become an important research area, as catalyst recovery, recycling as well as product separation is easier under heterogeneous conditions. In this respect, the iron complex of the Schiff base HPPn 15 (HPPn = iVA -bis(o-hydroxyacetophenone) propylene diamine) was supported onto cross-linked chloromethylated polystyrene beads. Interestingly, the supported catalyst showed higher catalytic activity than the free metal complex (Scheme 8) [50, 51]. In terms of chemical stability, particularly with... 

This reaction is truly tempting because it potentially satisfies the need in the search for a way to reclaim the chemical value of a polyurethane recycle foam project [12, 13]. When a polyurethane foam is hydrolyzed, it gives aromatic diamine and polyether polyol, both in very crude forms. The diamine can be purified by regular means, but the crude polyether polyol cannot be easily cleaned up due to its polymeric nature. If this Ganem reaction can work well, the polyether polyol stream can be converted to a low-molecular-weight chemical, which can then be purified by conventional process such as distillation. Indeed, when this reaction was tried on a polyether triol of 3000 molecular weight as a model, the diacetate of propylene glycol was isolated by distillation. Unfortunately, the yield was too low to be of practical interest. 

It is insoluble in water, microcrystallinc, and lilac in colour.1 Many of these derivatives of platinum containing organic bases have been obtained in optically active forms. Those containing 1-propylene-diamine will serve as examples. These are easily prepared, and as they are remarkably stable are easily examined for optical properties. The compounds are prepared by the interaction of cis-dichloro-l-propylenc-diamino-platinum, [Pt pnCl2], with the calculated quantity of the corresponding base, 1-propylcnediamine, ammonia, ethylenediamine, or trimethylenediamine. The liquid obtained is evaporated on a water-bath and precipitated with alcohol. The di-derivative of 1-propylene-diamine, [Pt pns]Cla, has rotation [a]o+46-37°, [M]r>+192-0°.
