Butyl-heptyl-methyl

Bei einzelnen N-Methylierungen erzielt man etwas hohere Ausbeuten, wenn man anstelle von Lithium-dimethylcuprat das aus Kupfer(I)-jodid und Methyl-magnesiumchlorid er-haltliche Methylkupfer einsetzt1 z.B. bei der Herstellung von Butyl-heptyl-methyl-amin (52%) ... 

Discriminative stimulus effect. Rhesus monkeys, trained to discriminate A-9-THC from vehicle in a two-lever drug discrimination procedure, were tested with a variety of psychoactive drugs, including cannabinoids or drugs from other classes. The results indicated that A-9-THC discrimination showed pharmacological specificity, in that none of the noncannabinoid drugs fully substituted for A-9-THC. The classical cannabinoids, A-9-THC and A-8-THC, and the novel cannabinoids, WIN and l-butyl-2-methyl-3-(l-naphthoyl)indole, produced full dose-dependent substitution for A-9-THC in all monkeys. A heptyl indole derivative failed to substitute for A-9-THC, but it also did not displace pH] CP-55,940 from its binding site . ... 

Experiments have been carried out with the rotating cryostat to study the reaction of 2,6-di-t-butyl-4-methyl phenol (lonol) with n-heptyl and n-heptylperoxy radicals. When lonol was deposited on n-heptyl radicals the e.s.r. spectrum showed that some reaction had occurred at 77°K. When the deposit was warmed slowly the spectrum of the residual n-heptyl radicals disappeared and was replaced by that of the substituted phenoxy-radical, (4), formed by loss of the hydroxyl hydrogen.

Examination of the venom content of the workers of Solenopsis maboya revealed the presence of (5Z,9Z)-3-butyl-5-methylindolizidine (107), (5E,9E)-3-butyl-5-methylindolizidine (108) and frans-2-methyl-6-nonylpiperidine (109), while analysis of the extract of the queens revealed the presence of a single alkaloid, ris-2-heptyl-5-methylpiperidine (110) (Fig. 19) [117]. Such caste-specific alkaloidic contents has been already been found in other Solenopsis ants [ 118,119] and suggest different roles for these compounds in each caste.

ControUed-potential oxidations of a number of primary, secondary, and tertiary alkyl bromides at platinum electrodes in acetonitrile have been investigated [10]. For compounds such as 2-bromopropane, 2-bromobutane, tert-butyl bromide, and neopentyl bromide, a single Ai-alkylacetamide is produced. On the other hand, for 1-bromobutane, 1-bromopentane, 1-bromohexane, 1-bromo-3-methylbutane, and 3-bromohexane, a mixture of amides arises. It was proposed that one electron is removed from each molecule of starting material and that the resulting cation radical (RBr+ ) decomposes to yield a carbocation (R" "). Once formed, the carbocation can react (either directly or after rearrangement) with acetonitrile eventually to form an Al-alkylacetamide, as described above for alkyl iodides. In later work, Becker [11] studied the oxidation of 1-bromoalkanes ranging from methyl to heptyl bromide. He observed that, as the carbon-chain length is increased, the coulombic yield of amides decreases as the number of different amides increases.

The parabens also show increased binding affinity with increased chain length. Thus, 2-ethylhexyl, heptyl, and benzyl 4-hydroxybenzoates showed greater affinity for the ER than those with shorter side chains (butyl, propyl, ethyl, and methyl 4-hydroxybenzoates).

Parabens are alkyl esters of p-hydroxyben-zoic acid. The alkyl groups may be one of the following methyl, ethyl, propyl, butyl, or heptyl. Parabens are colorless, tasteless, and odorless (except the methyl paraben). They are nonvolatile and nonhygroscopic. Their solubility in water depends on the nature of the alkyl group the longer the alkyl chain length, the lower the solubility. They differ from benzoic acid in that they have antimicrobial activity in both acid and alkaline pH regions. 

The lower members of the series, where R = methyl to n-propyl, have all-trans conformations in the solid at ordinary temperatures, as do the polymers where R = n-hexyl, n-heptyl, and n-octyl. The two polymers with intermediate chain length, R = n-butyl and n-pentyl, instead have a 7/3 helical stracture at room temperature. Yet another conformation, alternating trans-gauche (TG-TG ), is found for the polymer where R = n-tetradecyl. Above some... 

In order to have several dilferent positions available a study of some derivatives of heptane was begun. In the normal heptane it is possible to have a single substituent in four different positions in the molecule. The dipole moments of the four alcohols, heptanol-i ( -heptyl alcohol), heptanol-2 (methyl-/z-amy 1-alcohol), heptanol-3 (ethyl-/z-butyl-alcohol) and heptanol-4 (dipropyl-carbinol) have been measured. 

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.
