The first reports of metabolic labeling appeared in 1999. In this procedure, yeast cells were grown in two media, one of which used N-emiehed media. " The two yeast cultures were combined and the proteins of interest were digested with trypsin before mass speetrometry analysis. The labeling by use of an N-ammonium salt results in the eomplete labeling of amino acid and could be quantified with mass spectrometry. The corresponding mass shift between the unlabeled and the labeled form of the peptide requires high resolution mass spectrometry for analysis.

An explanation of the exclusive N methylation of 1,2-dimethyl-J -piperi-deine by means of methyliodide is more difficult. Pyrrolines and piperideines which are not alkylated on the nitrogen atom afford only quaternary ammonium salts on alkylation (203-205), for example 119.

The n values were high for all of the ionic liquids investigated (0.97-1.28) when compared to molecular solvents. The n values result from measuring the ability of the solvent to induce a dipole in a variety of solute species, and they will incorporate the Coulombic interactions from the ions as well as dipole-dipole and polarizability effects. This explains the consistently high values for all of the salts in the studies. The values for quaternary ammonium salts are lower than those for the monoalkylammonium salts. This probably arises from the ability of the charge center on the cation to approach the solute more closely for the monoalkylammonium salts. The values for the imidazolium salts are lower still, probably reflecting the delocalization of the charge in the cation. 

A new ionic polymeric polycarbamate was synthesized after steps of polyurethane chemistry using 3-iso-cyanatemethyl-3,5,5-trimethylcyclohexyl isocyanate, 2,5-dimethyl-2,5-dihydroperoxyhexane, 1,6-butanediol, 2,4-tolylenediisocyanate, and N,N -bis(j3-Hydroxy-ethyOpiperazine [27]. Modification of the nitrogen of the piperazine ring into quaternary ammonium salt by treatment with methyliodide gave the MPI high electroconductivity. 

Cupferron (ammonium salt of N-nitroso-A -phenylhydroxylamine). The reagent is used in cold aqueous solution (about 6 per cent). Metal cupferrates are soluble in diethyl ether and in chloroform, and so the reagent finds wide application in solvent-extraction separation schemes. Thus Fe(III), Ti, and Cu may be extracted from 1.2 M HC1 solution by chloroform numerous other elements may be extracted largely in acidic solution.
