H/D exchange reactions between C6D6 and C5Me5Co(CH2=CHR)2 (R = H, SiMe3): Evidence for oxidative addition of bonds to the [C5Me5(L)Co] moiety
摘要:
Heating C(5)Me(5)Co(CH2=CHR), (R=H, 60 degrees C; R = SiMe(3), 20 degrees C) in C6D6 leads to deuterium incorporation in the vinylic sites of the olefin ligands. This observation is interpreted in terms of reversible oxidative addition of C6D6 to the 16-electron species [C(5)Me(5)Co(CH2 = CHR)].
