 Dear List Members,

I need to remove PPh3 from the reaction mixture. Literature
references suggest using CuCl leading to insoluble complexes
with the phosphine ("PPh3 scavenger").
CuCl works well, however it is air sensitive and usually should
be freshly purified. That makes difficulties in some cases.

Are there any other PPh3 scavengers? Perhaps, the other way
to remove PPh3 from reaction mixture?

Thanks!

best regards, Valentine.
