^aEach reaction was ran on a 0.1 mmol scale in a sealed 4 mL vial, using 5 mol% [Rh(CO)₂Cl]₂ and 12 mol% P(C₆F₅)₃, in 1,4-dioxane (1.5 mL), at 130 °C, for 18 h.

^bYields of isolated products.

^cThe number in parentheses represents the yield based on recovered starting material (brsm).

^dThe ratio was determined by ¹H NMR.

^eThe structure of 5c was confirmed by a series of 2D NMRs, DEPT, and HRMS.

^f5h′ and 5i were isolated as a single olefin-geometric isomer; the exact olefin geometry for each was not determined.
