PV–CF2– transfer reagents is disclosed, with multigram scale reactions included. Condition-dependent divergent reactivity under the established conditions is demonstrated by the formation of trifluoromethylphosphines. Both one-pot transformations are operationally simple and employ inexpensive materials. Mechanistic investigations suggest the divergent reactivity originates from a common intermediate,
