Abstract

H2C:CHCH2OR (R = tetrahydropyranyl) gave a mixt. of H2C:CHCHR1OH and R1CHCH2CHO after metalation and reaction with an electrophilic agent R1X, whereas metalation of MeCH:CHOR (R = tetrahydropyranyl) with EtCHMeLi, followed by reaction with MeI and acid hydrolysis gave EtCOMe. The electrophile in the latter case could also be an alkyl halide, oxirane, carbonyl compd., nitrile, or CO2. [on SciFinder (R)]

Haloalkane

The haloalkanes (also known as halogenoalkanes or alkyl halides) are alkanes containing one or more halogen substituents. They are a subset of the general class of halocarbons, although the distinction is not often made. Haloalkanes are widely used commercially. They are used as flame retardants, fire extinguishants, refrigerants, propellants, solvents, and pharmaceuticals. Subsequent to the widespread use in commerce, many halocarbons have also been shown to be serious pollutants and toxins.

Acyl halide

In organic chemistry, an acyl halide (also known as an acid halide) is a chemical compound derived from an oxoacid by replacing a hydroxyl group () with a halide group (, where X is a halogen). If the acid is a carboxylic acid (), the compound contains a functional group, which consists of a carbonyl group () singly bonded to a halogen atom. The general formula for such an acyl halide can be written RCOX, where R may be, for example, an alkyl group, CO is the carbonyl group, and X represents the halide, such as chloride.

Aryl halide

In organic chemistry, an aryl halide (also known as haloarene) is an aromatic compound in which one or more hydrogen atoms, directly bonded to an aromatic ring are replaced by a halide. The haloarene are different from haloalkanes because they exhibit many differences in methods of preparation and properties. The most important members are the aryl chlorides, but the class of compounds is so broad that there are many derivatives and applications. Aryl chlorides are the aryl halides produced on the largest scale commercially: 150,000 tons/y in the US alone (1994).
