QHsBr + OH (aq) —v- C2H6OH + Br (aq) (5) This reaction may seem similar to the reaction between aqueous HBr and NaOH but there are two important differences. The ethyl bromide reaction is very slow (about one hour is needed for the reaction) and it occurs between a covalent molecule (C2H5Br) and an ion (OH-). In contrast, the reaction between HBr and NaOH in water occurs in a fraction of a second and it involves ions only, as shown in reaction (6). [Pg.330]

Nicotinic acid and related compounds react with l-chloro-2,4-dinitrobenzene in the manner of the cyanogen bromide reaction to yield derivative I, which possibly also decarboxylates at elevated temperature. In alkaline medium this derivative first adds an hydroxyl ion and then undergoes ring opening to yield the colored derivative II. [Pg.71]

The rate constant for the alkyl bromide reaction is equal to the slope of the line. The best way to determine a slope is by doing a linear curve fit using a spreadsheet or graphing calculator. Somewhat less accurately, any two points on the line determine the slope ... [Pg.1067]

A very important microwave-specific effect was evidenced in the absence of a base for the reaction of pyrazole with phenethyl bromide (reaction times MW = 8 min, A = 48 h, Eq. 41). When the same reaction was performed in the presence of KOH, the microwave effect disappeared (vide supra, Eq. 26). [Pg.93]

Evidence for a free radical pathway in the foregoing cycloalkyl bromide reactions was secured by San Filippo and coworkers, who found that cis and iraws-4-r-butylcydohexyl bromide afford nearly identical product mixtures with MesSnLi, MesSnNa and MesSnK under a given set of conditions (Table 7)45. Of the various combinations examined, that of di-bromide and Me3SnLi appeared to be most favorable to S/v2 displacement. [Pg.220]

Ca—H(D) stretching vibrations is slightly larger than the decrease in the contribution due to the C —H(D) bending vibrations. A typical relationship is shown for the chloride ion-methyl bromide reaction in Fig. 2. [Pg.151]

An example of C—Si bond formation concludes this overview of carbon heteroatom bond formation. Reflux of bromide 62 in benzene and in the presence of small amounts of (TMS)3SiH and AIBN afforded the silabicycle 63 in 88 % yield (Reaction 7.64) [76]. The key step for this transformation is the intramolecular homolytic substitution at the central silicon atom, which occurred with a rate constant of 2.4 x 10 s at 80 °C (see also Section 6.4). The reaction has also been extended to the analogous vinyl bromide (Reaction 7.65) [49]. [Pg.169]

Benzyl-6-methylcyclohexanone has been prepared by the hydrogenation of 2-benzylidene-6-methylcyclohexanone over a platinum or nickel catalyst, and by the alkylation of the sodium enolate of 2-formyl-6-methylcyclohexanone with benzyl iodide followed by cleavage of the formyl group with aqueous base. The 2,6-isomer was also obtained as a minor product (about 10% of the monoalkylated product) along with the major product, 2-benzyl-2-methylcyclohexanone by successive treatment of 2-methylcyclohexanone with sodium amide and then with benzyl chloride or benzyl bromide. Reaction of the sodium enolate of 2-formyl-6-methylcyclohexanone with potassium amide in liquid ammonia formed the corresponding dianion which was first treated with 1 equiv. of benzyl chloride and then deformylated with aqueous base to form 2-benzyl-2-methylcyclohexanone.i ... [Pg.105]

When cyclohexanone oxime 6e was used as amination reagent, primary amines were obtained from phenylmagnesium bromide. Reaction of 6e with alkyl Grignard reagents gave aziridines, whereas reaction with phenyllithium gave aziridine and the addition product of phenyllithium to the imine (Scheme 57) 24. [Pg.334]
