with apologies to T.S. Eliot:
...No! I am not Grubbs' catalyst, nor was meant to be;
Am an attendant molecule, one that will do
To fill a scheme, make a bond or two,
Accompany an ion; no doubt, an easy tool
Deferential, glad to be of use,
Crystalline, cautious, and alkyl-filled;
Full of non-polarity, but a bit basic;
At times, indeed, almost a ligand --
Certainly, at times, a Salt.
Shall I part my chains behind? Shall I put them in my reach?
I shall wear my charges proudly, and walk upon the beach.
I have seen the products bonding, each to each.
I do not think that they will bond to me.
