Iron hahdes react with haHde salts to afford anionic haHde complexes. Because kon(III) is a hard acid, the complexes that it forms are most stable with F and decrease ki both coordination number and stabiHty with heavier haHdes. No stable F complexes are known. [FeF (H20)] is the predominant kon fluoride species ki aqueous solution. The [FeF ] ion can be prepared ki fused salts. Whereas six-coordinate [FeCy is known, four-coordinate complexes are favored for chloride. Salts of tetrahedral [FeCfy] can be isolated if large cations such as tetraphenfyarsonium or tetra alkylammonium are used. [FeBrJ is known but is thermally unstable and disproportionates to kon(II) and bromine. Complex anions of kon(II) hahdes are less common. [FeCfy] has been obtained from FeCfy by reaction with alkaH metal chlorides ki the melt or with tetraethyl ammonium chloride ki deoxygenated ethanol. 

Reaction of ethyl chloride with an alcohoHc solution of ammonia yields ethylamine, diethylamine, triethylamine, and tetraethyl ammonium chloride (10,11) (see Amines, lower aliphatic). 

Somljo Some of you may remember that there was an old-fashioned drug called TEA (tetraethyl ammonium chloride). When this was applied to smooth muscle that normally didn t generate action potentials, it caused beautiful action potentials and rhythmic contractions. I don t think this was physiological.

The experiments were performed with single crystal (111) p-Si electrodes with a resistivity of about 5.5 ohm cm non-aqueous electrolytes were used consisting of absolute methanol containing tetramethylammonium chloride (TMAC) or acetonitrile containing tetraethyl ammonium perchlorate (TEAP). The flat-band potentials or p-Si in the two electrolytes were determined from Mott-Schottky plots (in the dark) in the depletion range of the p-Si electrode, from open-circuit photopotential measurements, and from the values of electrode potential at which anodic photocurrent is first observed in n-type Si electrodes. These three methods all yielded consistent flat-band potential values for p-Si of + 0.05V (vs SCE)... 

In another report, several acetylcholinesterase (AChE) inhibitors, including tacrine, edrophonium, tetramethyl- and tetraethyl-ammonium chloride, carbofu-ran, and eserine were assayed on a chip [1045]. AChE converted the substrate, acetylthiocholine, to thiocholine. This product reacted with coumarinylphenyl-maleimide (CPM) to form thiocholine-CPM (a thioether) for LIF detection. Since the acetonitrile solvent used to dissolve CPM inhibited AChE activity, the CPM solution was added after the enzymatic reaction [1045]. Another enzyme inhibition assay using a peptide substrate was performed on a PMMA chip [1046]. 

The polycarbonate oligomers were prepared by solution or interfacial techniques (10,17,18). Methylene chloride and tetraethyl ammonium chloride served as the solvent and phase transfer catalyst, respectively. The block copolymerizations were performed essentially under interfacial reaction conditions. In the case of copolymerizations using the Bis-S polysulfone oligomers, it was necessary to use tetrachloroethane as the organic solvent. 

An interesting example where infrared O-H frequencies were used to correlate structures is for choline chloride dihydrate, which is postulated to have a semi-clathrate hydrate structure by analogy with the known crystal structure of tetraethyl ammonium fluoride pentahydrate [162]. 

Commercially available tetraethyl orthosilicate (TEOS), dodecyltrimethyl- ammonium chloride (DTMACl) and trimethylammonium hydroxide (TMAOH) were mixed in water and the solution was stirred for 4 h at room temperature. The composition of the gel mixture was Si DTMACl TMAOH H2O = 1 0.6 0.3 60. White precipitates were filtered and dried at 393 K. This as-synthesized powder was calcined at 903 K for 4 h to obtain MCM-41. The silica was stirred vigorously in toluene containing a monolayer equivalent amount (1.0 per 1 nm ) of [l-(2-aminoethyl)-3-aminopropyl]trimethoxysilane...

Such a decomposition probably occurs in the case of all substances belonging to the NH3+HGI type at least the vapor density of ammonium chloride, of phosphorus pentachloride, etc. suggest that these bodies do not vaporize without decomposition, that their vapor in fact is a mixture of two vapors, which recombine when the temperature is lowered, as has been demonstrated with certainty in the case, for instance, of tetraethyl ammonium iodide. [The same view is expressed in the March issue of the Armalen, 105, 390 ff, the present article of Kekuld reached the editors after the closing of that issue but before its publication.— D.R.]...

Addition to quinonesA In the presence of catalytic amounts of tetraethyl-ammonium chloride or tetrafluoroborate, halotrimethylsilanes react with 1,4-benzoquinones (1) in CHaCN to give, after hydrolysis, halohydroquinones (2) in yields of 75-957o (equation I). The intermediate adducts can be converted into disilyl ethers (3).
