75 ± 0.12) for the reaction with ethylene but no significant isotopeeffect (kH/kD = 1.06 ± 0.07) for the reaction with propylene. We use density functional theory in its B3LYP and mPW1PW91 forms with a large basis set to characterize stationary points on the doublet potential energy surface for the reaction Y + C2H4 → YC2H2 + H2. Theory finds no energy barrier to the formation of a long-range Y−ethylene
