Abstract

Reaction of NaBEt with RhC1 (C2H4)(triphos)(I), where triphos is MeC (CH2PPh2) 3, gives RhH-(C2H4)(triphos). Coordinated 13C2H4 in labeled I is liberated during the reaction, proving that NaBEt, is the source of the ethylene coordinated in the product. Compound I reads at 1 atm and 25 OC with 13C2H4 or H2 to give RhC1 ('SCzH4)(triphos) or Rh (H) 2Cl (triphos), respectively. It is proposed that all three reactions proceed by a mechanism in ...
