2,3-Butanediamine
2,3-Butanediamine are organic compounds with the formula CH3CH(NH2)CH(NH2)CH3. Three stereoisomers exist, meso and a pair of enantiomers. These diamines form complexes with transition metals. Synthesis 2,3-Butanediamines can be prepared by hydrolyzing 2-ethoxy-4,5-dihydro-4,5-dimethylimidazole with barium hydroxide. Alternative, it is produced by reduction of dimethylglyoxime with lithium aluminium hydride. The meso and the d,l diastereomers can be separated by fractional crystallization of the hydrochlorides. The enantiomers have been resolved using tartrate salts. Reactions In coordination chemistry, 2,3-butanediamine (abbreviated bn) has illuminates aspects of the stereochemistry. The structure of o(meso-2,3-butanediamine)2CO3sup>+ confirms the presence of the rarely observed axial methyl groups on each of the diamine-cobalt rings.

1,2-Dimethylethylenediamine
N,N'-Dimethylethylenediamine (DMEDA) is the organic compound with the formula (CHNH)CH. It is a colorless liquid with a fishy odor. It features two secondary amine functional groups. Regarding its name, N and N' indicate that the methyl groups are attached to different nitrogen atoms. Reactions DMEDA is used as a chelating diamine for the preparation of metal complexes, some of which function as homogeneous catalysts. The compound is used as a precursor to imidazolidines by condensation with ketones or with aldehydes: : DMEDA complexes of copper(I) halides are used to catalyze C-N coupling reactions.

Putrescine
Putrescine is an organic compound with the formula (CH2)4(NH2)2. It is a colorless solid that melts near room temperature. It is classified as a diamine. Together with cadaverine, it is largely responsible for the foul odor of Putrefaction, putrefying flesh, but also contributes to other unpleasant odors. Production Putrescine is produced on an industrial scale by the hydrogenation of succinonitrile. Biotechnological production of putrescine from a renewable feedstock has been investigated. A metabolically engineered strain of ''Escherichia coli'' that produces putrescine at high concentrations in glucose mineral salts medium has been described. Biochemistry Spermidine synthase uses putrescine and S-Adenosylmethioninamine, ''S''-adenosylmethioninamine (decarboxylated S-Adenosyl methionine, ''S''-adenosyl methionine) to produce spermidine. Spermidine in turn is combined with another ''S''-adenosylmethioninamine and gets converted to spermine. Putrescine is synthesized in small q ...

Molecular Formula
A chemical formula is a way of presenting information about the chemical proportions of atoms that constitute a particular chemical compound or molecule, using chemical element symbols, numbers, and sometimes also other symbols, such as parentheses, dashes, brackets, commas and ''plus'' (+) and ''minus'' (−) signs. These are limited to a single typographic line of symbols, which may include subscripts and superscripts. A chemical formula is not a chemical name since it does not contain any words. Although a chemical formula may imply certain simple chemical structures, it is not the same as a full chemical structural formula. Chemical formulae can fully specify the structure of only the simplest of molecules and chemical substances, and are generally more limited in power than chemical names and structural formulae. The simplest types of chemical formulae are called '' empirical formulae'', which use letters and numbers indicating the numerical ''proportions'' of atoms of ...
