- W4251980147 abstract "Dially(4-fluorophenyl)phosphine and allyl(t-butylamino)phenylphosphine were pyrolyzed in a stirred-flow reactor at 340–420°C/9–19 Torr, using toluene as carrier gas. The primary reaction products were propene, 1-(4-fluorophenyl)-1-phosphabutadiene, and 1-phenyl-2-t-butyliminophosphine. The phosphorus-containing products gave rise to [4 + 2] and [2 + 2] cycloaddition products, respectively. The consumption of these phosphines showed first-order kinetics, with the rate coefficients following the Arrhenius equations: Dially(4-fluorophenyl)phosphine: k(s−1) = 109.00±0.32 exp (- 122 ± 4 kJ/mol RT) Allyl(t-butylamino)phenylphosphine: k(s−1) = 109.04±0.25 exp (-113 ± 3 kJ/mol RT) The results support a six-center cyclic transition-state unimolecular elimination reaction mechanism for both reactants. © 1997 John Wiley & Sons, Inc." @default.
