That is a fairly common reaction. PCl3 + Cl2 PCl5orDiethyl diazodicarboxylate + PPh3 hydrazide + triphenylphosphine oxideRe: Electron donation to oxygen of carbonylI generally think of carbonyl groups having a resonance structure with a negative charge on the oxygen and positive on carbon. Hence, ...
I do concede that upon searching, it is not difficult to find the proposed mechanism for a Reformatsky reaction. I had been taught that it inserted into the C-Br bond, but that should not be important. Since it now appears that a Zimmerman-Traxler transition state exists for addition of a...
