2-phenylethyl methyl

Benzylic deprotonation is often an inefficient process. It may be more important than it would appear from the end products, however, since radical cation deprotonation followed by reduction of the radical and reprotonation may regenerate the starting material. This mechanism has been proposed to explain the inefficiency of some PET alkylations [68]. In suitable models such a process has been revealed, e.g. deuterium incorporation at the bis-benzylic position in 2-(4-methoxyphenyl)-2-phenylethyl methyl ether and cis-trans isomerization in 2-methoxy-l-(4-methoxyphenyl)indane (but not in the corresponding 3-methoxyphenyl derivatives) [204], as well as deconjugation of 1-phenylalkenes to 3-phenylalkenes in the presence of 1,4-dieyanobenzene, biphenyl (as a secondary donor) and a hindered pyridine as the base [205]. Deprotonation of N,N-dimethylaniline has likewise been observed (Scheme 38) [206-207],... [Pg.164]

Jorgenson (282) isolated the following substances from red fox urine isopentenyl methyl sulfide (60), 2-phenylethyl methyl sulfide (61), 6-methyl-5-hepten-2-one (62) and /ra -geranylacetone (63) from both sexes and additionally 2-methylquinoline (64) from urine of males. [Pg.16]

In turn, photosensitized electron transfer fragmentation of a benzylic bond has been among the first reaction reported when this branch of photochemistry began to take shape in the seventies, with the decarboxylation of phenylacetic acids reported by Libman [23] and the C-C cleavage in phenylethyl methyl ethers reported by Arnold [24].

Reactions of a-lithio-sulphoxides have been studied, in an attempt to exploit the synthetic possibilities based upon different exchange rates of the a-methylene protons in an alkyl sulphoxide R CH2 SO R and the effects of solvent upon the exchange rates. (S )-( + )-Benzyl methyl sulphoxide (103) gives the (5, 5 )-a-lithio-derivative (104) with MeLi-THF at - 60 °C quenching with DgO and oxidation to the sulphone (105) with /w-chloroperbenzoic acid gives laevorotatory material, while (R)-( + )-phenylethyl methyl sulphone (106) is obtained by successive methylation (Mel) and oxidation. With benzyl t-butyl sulphoxide (103 Bu in place of Me), the (R,5 )-a-lithio-derivative is formed, which gives the (S )-(-)-phenylethyl t-butyl sulphone by successive methylation and oxidation. The possibilities of using this process in asymmetric syntheses are certain... [Pg.48]
