The action of methyl iodide on chloro-substituted heterocychcs usually results, in addition to quatemization, in the replacement of the chlorine by iodine if the halogen is in a position alpha or gamma to the quaternary center, particularly so in the former case. This type of replacement is less likely if dimethyl sulfate is used but may still occur to give a sulfate betaine (see Section IV, C). An easy method to obtain a-halogeno-quatemary salts has recently been discovered by Balli and Kersting who reacted the readily accessible triethyloxonium borofluoride 12 with a variety of bases. The very...

The formulation for use in the Swedish Army rifle contained Guncotton 96.2, sol cotton 1.8, resin, a stabilizer and other materials 2.0%. These propints were very stable, nearly hygroscopic, and produced much lower temps than corresponding double-base powders such as Cordite, Ballis-tite, etc. As a result, gun barrel life was lengthened... 

Balli and Felder (1978) and Balli and Ritter (1981) showed that diazo transfer can be applied advantageously to the diazotization of sufficiently nucleophilic heteroaromatic compounds such as 5-hydroxy- and 5-amino-3-methyl-l-phenyl-pyrazole if 3-ethyl-2-azido-benzthiazolium tetrafluoroborate (2.50) is used as diazo transfer reagent (for other applications of this diazo transfer reagent see Zollinger, 1995, Secs. 2.6-2.8). The diazonio group is introduced in the 4-position (2.51).
