Organorhenium Oxides,Pd) present well-known examples to demonstrate the importance of organometallic model systems for a better understanding of catalytic mechanisms. This is still true even when safe conclusions for heterogeneous processes cannot be drawn from stoichiometric reactions carried out at soluble (homogeneous) species.作者: 貧窮地活 時間: 2025-3-22 03:43 作者: Endoscope 時間: 2025-3-22 06:31
Olefin Insertion into Organyl Metal Bonds,H.CH.)nEt. This mixture is statistically controlled because triethylaluminium and all intermediates (n =1 to n) during this reaction have similar reactivities towards ethylene.. If the M-R bond at the beginning is much more reactive than the M-C bond of the first insertion product, the reaction would terminate after the first step (Scheme 1).作者: 虛構(gòu)的東西 時間: 2025-3-22 10:57 作者: obeisance 時間: 2025-3-22 13:59
