Salt primary

We ve already studied the two most general reactions of amines—alkylation and acylation. As we saw earlier in this chapter, primary, secondary, and tertiary amines can be alkylated by reaction with a primary alkyl halide. Alkylations of primary and secondary amines are difficult to control and often give mixtures of products, but tertiary amines are cleanly alkylated to give quaternary ammonium salts. Primary and secondary (but not tertiary) amines can also be acylated by nucleophilic acyl substitution reaction with an acid chloride or an acid anhydride to yield an amide (Sections 21.4 and 21.5). Note that overacylation of the nitrogen does not occur because the amide product is much less nucleophilic and less reactive than the starting amine.

It is well known that halomethyleneiminium salts, often prepared in situ (see Section 2.1.2.2) react with ammonium salts, primary amines, secondary amides, urea and IV-substituted ureas to afrbrd amidinium salts, from which the free amidines can be obtained by addition of bases. > 4 Some recent results are given below. Dimethylformamide chloride and other 7V,iV-disubstituted formamide chlorides were reacted with acetanilides, chloroacetanilides, 6-aminopenam derivatives, 2-aminopyrimidine, 4-aminouracil, 2-amino-4-chloropyridazine, 2-aminothiazole, 2-aminobenzothiazole and thiobenzamides to give the amidines via the amidinium salts. In the reaction of MA -disubstituted formamide chlorides with thiobenzamides the solvent seems to be decisive for the course of the reaction. In tertiary formamides the thiobenzamides are desulfurized to nitriles, whereas in CHCI3 or CCI4 amidinium salts (296 Scheme 45) are formed. From trimethylsilyl isocyanate and the fluorinated amine (297) the /V-fluorocarbonylamidine (298) is accessible. ... 

Condensation reactions can be grouped into two categories. The first category involves pyrazol-3-ones with formyl, acyl, nitroso, a,jS-unsaturated oxo, 3-oxo-2-azobutyric acid ethyl ester or acetonitrile substituents at position 4 or formyl substituents at position 5 and their reaction with carbanions, heterocyclic methylcarbenium salts, primary and secondary amines, diamines, heterocyclic perchlorates, hydroxylamine, hydrazines, urea or thiosemicarbazide. The second category involves pyrazol-3-ones with amino, hydrazino, heteroaromatic amino, acetyl or acetonitiilo groups at position 4 and their reaction with aryl or heteroaromatic aldehydes or cyclic ketones. 

Fig. 34.13. Structures of the primary and secondary bUe salts. Primary bile salts form conjugates with taurine or glycine in the hver. After secretion into the intestine, they may be deconjugated and dehydroxylated by the bacterial flora, forming secondary bile salts. Note that dehydroxylation occurs at position 7, forming the deoxy family of bUe salts.

Orthophosphoric acid is a tribasic acid giving rise to three series of salts primary orthophosphates, e.g. NaH2P04 secondary orthophosphates, e.g. Na2HP04 and tertiary orthophosphates, e.g. Na3P04. If a solution of orthophosphoric acid is neutralized with sodium hydroxide solution using methyl orange as indicator, the neutral point is reached when the acid is converted into the primary phosphate with phenolphthalein as indicator, the solution will react neutral when the secondary phosphate is formed ... 

Both nitroalkane and aromatic nitro compounds can react with bases to produce salts. Primary nitroalkane reacts with concentrated NaOH to generate trialkyl is-oxazole [12].

Tertiary phosphines react with acyl halides (6.364), unsaturated aldehydes (6.365) and esters (6.98-6.100), and with carbon tetrachloride (6.92) to produce phosphonium salts. Primary and secondary phosphines can be sources of phosphonium salts (6.93,6.94) as can tertiary phosphines.

Amines and amine salts. Primary, secondary and tertiary amines proton-ate to give positive ions corresponding to the amine salt [RiR2R3NH] . This cation can also lose two hydrogen atoms to give an ion that could be confused with that from an unsaturated analogue. The presence of such ions should be taken into account before the determination of unsaturated species is attempted. 

Among possible combinations of nuclear fuel, coolant and energy conversion equipment for a NPP that is to operate in a remote and hard-to-access area, the combination of coated particle based graphite fuel elements and a molten salt primary circuit coolant based on Li, Na, Be, and Zr fluorides and a gas turbine unit for electricity generation may offer special advantages. 

The efficiency of a surfactant in platelet exfoliation and interfacial bonding should be considered as the main criterion for its selection. However, it is advisable to select a surfactant with respect to its thermal stability a well. The number and length of alkyl chains, type of counterion, and class of amine (or ammonium salt) - primary, secondary, or tertiary - were considered important parameters influencing the thermal stability of nanocomposites.
