A novel and efficient approach to ortho‐trialkylstannyl arylphosphanes by the reaction of arynes generated in situ with stannylated phosphanes (R3SnPR2) is described. Concurrent CP and CSn bondformation occurs with high yields, and stannylated products are easily transformed into valuable ortho‐substituted arylphosphanes. The reaction features high efficiency, good regioselectivity, and excellent

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
