This property allows the convenient preparation of cobalamin analogs with different substituents, via nucleophilic attack on alkyl halides and vinyl halides.
32.
"' 1-Chlorobutane "'is an alkyl halide with the chemical formula C 4 H 9 Cl.
33.
Especially versatile methods included the addition of halogens to alkenes, hydrohalogenation of alkenes, and the conversion of alcohols to alkyl halides.
34.
For example, no reaction occurs between neopentyl chloride and, whereas the secondary alkyl halide analogs are too unstable to be isolated.
35.
Lead readily forms an equimolar alloy with sodium metal that reacts with alkyl halides to form organometallic compounds of lead such as tetraethyllead.
36.
The haloform reaction, using chlorine and sodium hydroxide, is also able to generate alkyl halides from methyl ketones, and related compounds.
37.
Hydroboration produces organoborane compounds that react with a variety of reagents to produce useful compounds, such as alcohols, amines, alkyl halides.
38.
Ivanov reagents ( dianions of aryl acetic acids ) react with many electrophiles, including aldehydes, ketones, isocyanates, and alkyl halides.
39.
In one study the kinetic isotope effect ( KIE ) was determined for the gas phase reaction of several alkyl halides with the chlorate ion.
40.
For instance, it is possible to get a contact ion pairs formed from an alkyl halide in which the ions are not fully separated.
