Trimethyl ammonium iodide

Butyryl choline iodide [(2-butyryloxyethyl)trimethyl ammonium iodide] [2494-56-6] M 301.7, m 85-89", 87", 93-94". Recrystd from isoPrOH or Et20. [Tammelin Acta Chem Scand 10 145 1956.] The perc/i/orate has m 72° (from isoPrOH). [Aldridge Biochem J 53 62 / 953.]... [Pg.517]

S-Butyryl thiocholine iodide [(2-butyrylmercaptoethyl)trimethyl ammonium iodide] [1866-16-6] M 317.2, m 173", 173-176". Recrystd from propan-l-ol and dried in vacuo store in the dark under N2. The bromide has m 150° (from Me2CO) or m 140-143° (from butan-l-ol). [Gillis Chem and Ind (London) 111 1957 Hansen Acta Chem Scand 11 537 1957.]... [Pg.517]

The o-quinodimethane (40) may also be generated by fluoride-induced 1/4/elimination of trimethyl(2-[(trimethylsilyl)methyl]-benzyl) ammonium iodide (43). When this elimination is carried out at low temperature, the reaction conditions are ecjually compatible with the presence of 27, and this provides an additional route to 42. ... [Pg.44]

Substantial shifts were observed in the spectra of Af-ethylquinolinium iodide, N-methylnicotinium iodide (72) and [3-(dunethylamino)propyl]trimethyl ammonium iodide with [Eu(fod)4]. In the case of 72, the relative magnitude of the shifts indicated that the cationic nitrogen was the site of association with [Eu(fod)4]" rather than the tertiary nitrogen coordinating directly with the Eu(III) °. ... [Pg.817]

Alternatively, the o-benzoquinodimethane may be generated by fluoride-induced 1,4-elimination from trimethyl[2-(trimethylsilylmethyl)benzyl]ammonium iodide (13a). Interception with l-bromo-2-chlorocyclopropene gave the adduct 15a in 38% yield.Tetrahalocy-clopropenes were, however, unreactive. This method of o-quinodimethane generation has also been applied to pyridine derivatives, and provided a short route to l//-cyclopropa[g]quino-linc (16b).The interception was unsuccessful when the approach was applied to cyclo-propaisoquinoline. ... [Pg.2892]
