organoheteroatom stannanes containing elements of the groups 15 (P, As) and 16 (Se) with perfluoroalkyl iodides (RfI) was studied. Herein, a one-pot two-step reaction to form P–Rf, As–Rf and Se–Rf bonds is reported. The stannanes n-Bu3SnZPhn (Z = P, As, Se; n = 1–2) were generated in situ by the reaction of the PhnZ− anion with n-Bu3SnCl. The cross-coupling reactions of these stannanes with RfI afforded
研究了Pd催化的含有15(P,As)和16(Se)组元素的有机杂原子锡烷与全氟烷基碘(R f I)的交叉偶联反应。本文报道了一锅两步反应形成P–R f,As–R f和Se–R f键的过程。的锡烷Ñ -Bu 3 SnZPh Ñ(Z =磷,砷,硒; Ñ = 1-2)产生原位由pH的反应Ñ ž -阴离子与Ñ -Bu 3的SnCl。这些锡烷与R f的交叉偶联反应我提供了C-杂原子产品,新的全氟烷基ar氨酸和全氟烷基硒化物,产率高(47-90%),全氟烷基膦的产率中等(15-48%)。
