Alkylation mono

Ion masses (m/z) of different molecular and adduct ions of alkyl mono- and diglucosides (as assigned in Figs. 2.7.2 and 2.7.5) (Reprinted from [1], Copyright 1999, with permission from Elsevier)... 

These a-functionalized lithiosilanes are stable for up to 6 days at 0°C, when at least one substituent at silicon is an aryl group. Alkylated mono- or diaminochlorosilanes, however, undergo with lithium in THF homocoupling reactions to yield the corresponding symmetrical di- and tetraaminodisilanes (equation 40)89. 

Perhaps the most interesting point which emerges from the results is that in ethylenes bearing electron-releasing alkyl substituents the ratedetermining step appears to be a nucleophilic process, as indicated by the positive p values. This does not contradict the assumption that the first step in the ozone—olefin reaction is an electrophilic attack of ozone on the carbon-carbon double bond. The present observations also agree with some of the results obtained recently by Pritzkow et al. (16) for alkyl mono-substituted ethylenes in ethanol solution at — 60 °C. 

When alkyl mono halides are treated with silver hydroxide, AgOH, or with potassium hydroxide, KOH, the halogen is replaced by the hydroxyl group and mono-hydroxy alcohols result. 

By using any other methyl alkyl mono-ketone other ie/a-di-ketones may be obtained. 

Lead tetra-alkyls containing one or two secondary radicles can easily be obtained by the action of lead alkyl mono- or dihalides on secondary magnesium alkyl halides, win 1st those containing three secondary radicles are derived ] )rimaril,y from the tctra-alkyls. Table XX. of the Appendix gives a list of these compounds, together with their physical constants. 

An extended range of synthons of stoichiometry M(OAr)5 and M(OAr)5 X (X = halo, alkyl mono-, or binuclear depending upon ligand bulk) are available as well as six-coordinate complexes M(OAr)5L (L = neutral donor). 1,309 In addition, the reaction of bulky aryloxides such as LiOAr (ArOH = 2,6-Me2-C6H3OH) with Nb2Cl10 produced both mononuclear [Li(thf)3][Nbv-Q-(OAr)4] (149) and binuclear [Li(thf)2]2 [NbIV(OAr)2Cl2]2(/i2-Cl)2 (150) species.310... 

Alkylated mono-Cp trichloride complexes Cp MCl3, Cp = l /l-Bu CsH M = Zr 288, Hf 289, and Cp = EtsCs, M = Zr 290, were synthesized by salt metathesis (Scheme 60). These compounds can be readily converted into the corresponding benzyl derivatives Cp Zr(CH2Ph)2Cl 291 or Cp Zr(CH2Ph)3 2 92.229 Refluxing a mixture of lithium...

Examples presented describe the separation and purification of naphthalene from its associated impurities, alkylated mono- and dicyclic aromatics. Supercritical pentane at 42 atm and 215 °C and a chromatography adsorbent of baked brick impregnated with polyethylene glycol (6000 molecular weight) are used to separate a 95% naphthalene-5 % alkylated aromatics mixture into a 99.5% naphthalene fraction of 70% yield and a concentrated impurities fraction of 10% of the feed. Approximately 20% of the product is recycled.

Screening methods for 44 nitro-, chloro-, and alkyl mono- and disubstituted phenolic compounds in water were developed on three columns cyanopropyl, C,g, and diphenyl (A = 220nm). A 60-min 50/50->90/10 methanol/water (lOmM acetate buffer at pH 4.8) gradient was used. Not all 44 compounds were baseline resolved, but a subset of 28 were resolved on the C g column using the above gradient. Detection limits were reported individually for all components and ranged from 0.5 to 1.7 ppm [105].

For a pure alkylmonoglycoside, DP = 1.0, by definition. Therefore the above DP value implies that the raw material is a mixture of alkyl mono-and polyglycosides.
