Water Loss from Molecular Protonated Ions of Benzyl 2-Phenylether and Derivates
Kingston, Eric E.,Shannon, James S.,Lacey, Michael J.
, p. 30 - 35 (1987)
The skeletal rearrangement for water loss is the dominant reaction in the chemical ioinization mass spectrum of benzyl 2-phenylethyl ether.Isotopic distribution obtained for this reaction with specifically labelled derivates have been interpreted in terms of competing five- and six-centered skeletal rearrangements.Chemical substitution of the altermative aromatic rings strtongly influences the balance of the competition.
Palladium-promoted arylation of functionalised organolithium compounds via their zinc derivatives
Yus, Miguel,Gomis, Joaquin
, p. 1989 - 1995 (2007/10/03)
The reaction of different functionalised organolithium compounds 2, 5, 8, and 13 [easily prepared by DTBB-catalysed lithiation of isochromane (1), phthalane (4), 2,3-dihydrobenzofuran (7) and 1-chloro-3,3-diethoxypropane (12), respectively] with an equimo
Negishi cross-coupling with functionalised organozinc compounds prepared by lithium-zinc transmetallation
Yus, Miguel,Gomis, Joaquín
, p. 5721 - 5724 (2007/10/03)
The reaction of some functionalised organolithium compounds 2 (easily prepared by DTBB-catalysed lithiation of isochroman, phthalan and 2,3-dihydrobenzofuran) with an equimolecular amount of zinc bromide followed by reaction with an aryl or alkenyl bromide in the presence of a catalytic amount of Pd(PPh3)4 or Pd(PPh3)2(OAc)2 (5 mol%) under THF reflux overnight gave the expected cross-coupling compounds. These arylation or alkenylation processes, which work also with iodinated substrates, are not possible in the absence of the zinc or palladium compounds under the same reaction conditions.
