Butyl-pentyl

A series of zinc diphosphonate complexes were synthesized in the presence of diamines of varying chain length. 1-hydroxyethylidenediphosphonate bridges the metal ions with the proto-nated diamine (ethyl-, butyl-, pentyl-, or hexylenediamine) filling in channels or residing between chains. All four structures are different with one-, two-, and three-dimensional networks formed. The coordination number (4-6) and geometry also varies.418...

Man erhalt auf diese Weise z. B. Benzyl-butyl-pentyl-amin (R1 = R2 = C4H9 Rs = CH2-C6H5 25%). Das Ausgangsreagenz stellt also ein CH2-N-Aquivalent dar. 

Bei der nachstehenden Reaktionsfolge zur C-Alkylierung eines sekundaren Methylamins wird iiber N-Lithiierung in mehreren Schritten ein Lithium-dithiocarbamat hergestellt, das noch im Reaktionsgemisch sauer zu Butyl-pentyl-amin (85%) hydrolysiert wird2. 

Compounds are systematically named in the density tables as alky (alkenyl, alkynyl, etc.) derivatives of benzene in the style <side chains>benzene. Side chains consist of one or more alkyl (alkenyl, alkynyl, etc.) radicals attached to the benzene ring. Thus names such as butyl, pentyl, heptyl refer to saturated straight chain radicals. Unsaturated side chains are named as radicals from the corresponding alkene, alkadiene, alkyne, etc. Examples are ethenyl, (1-propenyl), (2-butenyl), (2,3-pentadienyl), and (4-pentynyl). The numbers indicate the postion of the double and triple bonds. 

Bouquet-shaped CDs result from the grafting of 14 polymethylene chains to 3-monomethylated P-cyclodextrin, meaning seven chains on each side of the CD ring molecule [58], Per(2,6-di-(9-alkyl) CDs where the alkyl chain may be propyl, butyl, pentyl, 3-methylbutyl, or dodecyl also take part in the bouquet family [4],...

Reaction of fert-butyl pentyl ether [CH3CH2CH2CH2CH20C(CH3)3] with HBr forms 1 -bromopentane (CH3CH2CH2CH2CH2Br) and compound Z. Z has a molecular ion in its mass spectrum at 56 and gives peaks in its IR spectrum at 3150-3000, 3000-2850, and 1650 cm . Propose a structure for Z and draw a stepwise mechanism that accounts for its formation.

Other photolysis studies have been reported for ethyl iodide -propyl iodide and isopropyl iodide in the gas phase, and also in liquid and solu-tion . Solution and liquid phase studies have also been reported for butyl ° , pentyl and cetyl iodides ". The primary process in the photolysis of alkyl iodides has been further discussed by Donovan and Husain in reference to the formation of excited halogen atoms.

The R group methyl, ethyl, propyl, butyl, pentyl, vinyl, or phenyl (Scheme 1) influences the hydrolysis rate of the silane endcapping group. The size and the inductive effect of the substituents R, acetyl, methyl, ethyl, or imine modify the reactivity as well. 

The resorcinols used as starting materials in the present process are either resorcinol itself (III, R=H) or a 5-alkylresorcinol (III, R=alkyl). The alkyl group may have up to twelve carbon atoms and it may be either branched or straight-chained. Examples of such alkyl groups are methyl, ethyl, propyl, sec-butyl, pentyl, 1,1-dimethylbutyl, 1,2-dimethylbutyl, l-ethyl-2-methylpropyl, isohexyl, heptyl, 1-methylhexyl, 1,2-dimethylhexyl, 1,2-dimethylheptyl, 1-methyloctyl, and 1-methylnonyl. 

This list is exhaustive as far as non-carbon parent hydrides are concerned. A number of established shortened or entirely non-systematic names are also used for carbon-based hydrides methyl, ethyl, propyl, butyl, pentyl, hexyl, cyclohexyl, phenyl, naphthyl, etc. 

In the 1950s, it was reported that the reaction of cyclopropane with lithium aluminum hydride gave tripropylaluminum. However, this result was not verified. The reaction of cyclopropane in the vapor phase with diborane to monoalkylcyclopropanes was shown to be fairly regioselective, the products being derived from addition of the hydride to the most-substituted carbon atom, and the boron to the least-substituted carbon atom. With butyl-, pentyl- and octylcyclopropanes after oxidative workup the linear primary alcohols 3 were obtained as the major products together with small quantities of the 2-methyl derivatives 4.
