• Site selectivity in the β-scission of alkoxyphosphoranyl radicals. A reinterpretation
  作者：Brian P. Roberts、Karamjit Singh

  DOI：10.1039/p29800001549

  日期：——

  allowance is made for the retarding effect of the five-membered ring. β-Scission of TBP alkoxyphosphoranyl radicals thus involves equatorial site selectivity. Previous results for phosphoranyl radicals (A) and (B)(X = Me3SiO) are reinterpreted in terms of equatorial site selectivity rather than the apical site selectivity originally proposed. The apicophilicity of Me3SiO is almost certainly lower than
