4- Methylbenzyl chloride

Alkylation of the p-chloro analog (102) of the monosubsti-tuted piperazine with m-methylbenzyl chloride (103) yields the... [Pg.58]

As far as the reactions with benzyl chlorides are concerned (74), the oxidative addition of benzyl chloride and substituted benzyl chlorides to palladium atoms yields rj -benzylpalladium chloride dimers. The parent compound, bis(l,2,3-7 -benzyl)di-/i,-chloro-palladium(II), quantitatively adds four molecules of PEts by first forcing the rj -benzyl-iy -benzyl transformation, with subsequent breakage of the Pd-Cl bridges to form trans-bistPEtsKbenzyDchloroPddI). The spectral characteristics of the parent molecule are indicative of the allylic type of bonding. Similar i7 -benzyl compounds were formed from 4-methylbenzyl chloride, 2-chloro-l,l,l-trifluoro-2-phenylethane, and 3,4-dimethylbenzyl chloride. [Pg.160]

Very little is known concerning the stereochemistry of electrochemical reduction of simple acyclic halides. Eberson studied the reduction of optically active a-methylbenzyl chloride (11) in dimethylformamide (DMF) containing deuterium oxide 21K The a-deuterioethylbenzene (12) obtained from this... [Pg.11]

In the preparation of iodides, but not bromides, PMHS may be substituted for the TMDO. Chlorides can be obtained if thionyl chloride and zinc iodide are added to suppress the formation of symmetrical ethers.314 An example of this type of reductive chlorination is shown by the TMDO-mediated conversion of p-tolualdehyde into p-methylbenzyl chloride (Eq. 201).313 To obtain chlorides from aldehydes having electron-withdrawing groups such as nitro or carbomethoxy, the initial reaction is first carried out at —70° and the mixture is then heated to reflux in order to reduce the formation of symmetrical ether by-products. Zinc chloride is substituted for zinc iodide for the synthesis of chlorides of substrates with electron-donating groups such as methoxy and hydroxy.314... [Pg.73]

Further work to firmly establish which position loses a hydrogen atom in the gas-phase pyrolysis of a-chloro-u-xylene or omethylbenzyl chloride151 was undertaken by means of flash pyrolysis of o-methylbenzyl chloride-a,a-d2 at 750 °C152. The results as described in equation 66 indicated that the hydrogen atom is abstracted from the o-CH3 group. Consequently, the mechanism was rationalized in terms of a direct -elimination followed... [Pg.1095]
