    • The nonstatistical crossover is likely due to the different reaction rates of the two alkynes, and formation of insoluble silver halide salts could explain this discrepancy.

    • Alkynes 12 and 13 were combined under the reaction conditions, in the absence of silacyclopropane 1 and were shown to provide no deuterium scrambling.
