A slight excess of hexamethyldisilane added slowly under argon to a suspension of Na-methoxide in 1 -dimethyl-2-imidazolidone (as basic aprotic solvent) containing n-heptyl chloride, and the product isolated after an additional hr. -> n-heptyltrimethylsilane. Y almost 100%. F. e., also with K-methoxide in the presence of 18-crown-6 polyether, s. H. Sakurai and F. Kondo, J. Organometal. Chem. 92, C46 (1975) crown ether diemistry, review, s. G. W.

A kinetic study of the reactions of s-amyl iodide, j-amyl iodide, and n-heptyl chloride has been carried out in various aqueous ethanol solutions in the presence and absence of OH . For all three substrates, and E2 processes only are found when OH... 

Of the crystalline derivatives of thiols, those formed with 3 5-dinitro-benzoyl chloride are not very satisfactory since they have, in general lower melting points than those of the corresponding alcohols (compare Section 111,27,7) and do not diflfer widely from ethyl to n-heptyl. The best results are obtained with 2 4-dinitrochlorobenzene. 

Typical of the sort of data needed to determine whether additives affect the interface is that provided by a study of the influence of n-heptyl compounds on the gel structure of dispersions containing polar solids in nonpolar vehicles (70). The influence of the polar heptyl compounds on the fluidity of dispersions of rutile and a fine silica (HiSil) in a dibasic ester, Plexol 201, is shown in Fig. 7. Apparently, the more polar rutile adsorbs all except the chloride and in these cases thinning results. HiSil has a lower F value and adsorbs only the amine and alcohol preferentially. Greases prepared from the least polar solid, Aerosil, are also least influenced by these additives (or even by more complex ones). Measurements of the solution isotherms for HiSil and Aerosil reveal significant adsorption of heptyl alcohol, but no detectable chloride adsorption in the same concentration range. 

Surface properties of unmodified carbon-silica adsorbents (carbosils X, H, B, Y) and the same adsorbents modified with the products of pyrolysis of n-heptanol (H) and benzyl alcohol (B) in an autoclave (A) and dynamic reactor (R). The carbosils were prepared by the pyrolysis of methylene chloride adsorbents X and Y), n-heptyl alcohol (H) and benzyl alcohol (B) on the silica surface... 

Treatment of the diamide 77 with dibutyltin dichloride affords the 2,2-bis(2-[4(/ ),5(5)-diphenyl-1,3-oxazolinyl])propane 78, while successive reaction of 77 with mesyl chloride and aqueous ethanolic sodium hydroxide yields the diastereomer 79 <96TI3649>. The (+)- and (-)-forms of the chiral oxazoline 80 were used as ligands for palladium catalysed allylic amination reactions thus the acetate 81 and benzylamine gave the optically active amine 82 in excellent enantiomeric excess <97JOC55Q8>. The enantioselective catalytic alkylation of aldehydes RCHO (R = n-heptyl, Ph, cyclohexyl or PhCH=CH) with allyluibutyltin in the presence of chiral bis(oxazolinyl)zinc complexes, c.g., 83, leads to alcohols 84 in 40 6% enantiomeric excess <97TL145>.

A typical case is the growth of silver whiskers by cathodic reduction from concentrated silver nitrate solutions (0.3 M) containing certain organic additives such as oleic acid, gelatine, albumin, or n-heptyl, n-octyl, and -nonyl alcohols, or, from silver nitrate solutions aged for several weeks. Copper whiskers can be grown from solutions containing a variety of additives or hydroxylamine ions in the presence of chlorides. 

In our initial attempts to study the effect of (DODA) Chloride, (DODA)C, sonicated vesicles on the thiolysis of p-nitrophenylacetate (NPA) by n-heptyl mercaptan (HM) we found that metal from the probe catalyzed the oxidation of the mercaptan [Cuccovia, I.M., unpublished]. In order to avoid mercaptan oxidation we developed an alcohol injection method for the preparation of (DODA)C vesicles, that were characterized by gel filtration and by the incorporation of lipid soluble probes [15]. It is not clear, today, if the aggregates prepared by ethanol injection are highly permeable closed vesicles or other types of bilayer assemblies [16].
