Example The mass spectra of both acetone and butanone show typical acyiium ion peaks at m/z 43, whereas the signals in the spectra of isopropyl ethyl thioether (Fig. 6.9), of 1-bromo-octane, (Fig. 6.10), and of isomeric decanes (Fig. 6.18) may serve as examples for carbenium ion signals. The superimposition of both classes of ions causes signals representing an average pattern. The properties of larger carbenium ions are discussed in the section on alkanes (Chaps. 6.6.1 and 6.6.3). 

Using h NMR spectroscopy the complex-formation equihbria between halothane (2-bromo-2-chloro-l,l,l-trifluoroethane) and methyl tert-butyl ether or tetrahydrofu-ran in various inert solvents (hexane, heptane, decane, cyclohexane) were measured as a function of temperature (Tkadlecova et al., 1995). 

Substantial variations of the organic solvent used in triphase catalysis with polystyrene-bound onium ions have been reported only for the reactions of 1-bromo-octane with iodide ion (Eq. (4))74) and with cyanide ion (Eq. (3)) 73). In both cases observed rate constants increased with increasing solvent polarity from decane to toluene to o-dichlorobenzene or chlorobenzene. Since the swelling of the catalysts increased in the same order, and the experiments were performed under conditions of partial intraparticle diffusional control, it is not possible to determine how the solvents affected intrinsic reactivity. 

Derivatives of homocubanecarboxylic acids are selectively available from bis(a-halo ketones) with the bishomocubane skeleton by protection of the carbonyl functions. Thus, 5-bromo-10,10-(ethylenedioxy)pentacyclo[5.3.0.02,6.03,9.05 8]decan-4-one and the corresponding 1,5-di-bromo derivative gave 9,9-(ethyIenedioxy)pentacyclo[4.3.0.02 5.03-8.04,7]nonane-4-carboxyIic acid (6a)61 and the 1-bromo derivative 6b,62 respectively, in good yields. 

In this manner. l,5-dibromo-10,10-(elhylenedioxy)pentacyclo[5.3.0.02-5.0349.04 8]decan-6-one was converted to 8-bromo-9,9-(ethylenedioxy)pentacyclo[4.3.0.02 5.03-8.04-7]nonane-4-car-boxylic acid (9) in 92 % yield. After conversion to the a-bromo ketone, a repeated ring contraction using 25% aqueous potassium hydroxide gave dimethyl cubanedicarboxylate 10 in 25% yield after methylation with diazomethane.64...

Reduction of alkyl halides and tosylates,2,3 Reduction with sodium cyanoborohydride in HMPT provides a rapid and selective removal of iodo, bromo, and tosyloxy groups in high yield. Thus 1-iododecane can be reduced in this way to n-decane in... 

Bromo(cyclopropylidene)methyl]cyclohexene (29) was formed in low yield as a side product in the reaction of 10,10-dibromodispiro[2.0.5.1]decane (28) with tert-butyllithium. ... 

The 3-arsonopyruvic acid (3-arsono-2-oxopropanoic acid) 150 was prepared via the oxidation of 3-arsono-2-hydroxy-2-(hydroxymethyl)propanoic acid 151, which was obtained from the treatment of AS4O6 (arsenolite, arsenic(lll) oxide, 2,4,6,8,9,10-hexaoxa-l,3,5,7-tetratsatricyclo[3.3.1.1 ]decane 152) with 2-bromo-3-hydroxy-2-(hydroxymethyl)-propanoic acid 153 (Scheme 47) <1995BJ931>.
