WebAs for general compatibility. Anything with an aromatic nitrogen is going to do weird shit - it will coordinate to the phosphorus and split the LR into the monomer RP (=S)2Py for example if you add pyridine - this can make it far more reactive. So if your substrate had an aromatic nitrogen in it you could see LR reacting in ways you wouldn’t ... WebThis page was last edited on 22 September 2024, at 00:37.
