Terminal alkynes undergo oxidative cross‐coupling with secondary phosphine selenides in the presence of 3 mol% Pd(OAc) 2 and 1 equivalent of Et 3 N in CCl 4 at room temperature to provide alkynylphosp
Terminal alkynes undergo oxidative cross‐coupling with secondary phosphine selenides in the presence of 3 mol% Pd(OAc) 2 and 1 equivalent of Et 3 N in CCl 4 at room temperature to provide alkynylphosphine selenides in up to 65% yields. This new C sp P‐forming reaction was proved to proceed via intermediate chlorophosphine selenides.
