Other Reactions of RhCl(PPh3)3
RhCl(PPh3)3 reacts with CO to give trans-RhCl(CO)(PPh3)2, which is structurally analogous to Vaska's complex (but much less reactive). The same complex arises from the decarbonylation of aldehydes:
- RhCl(PPh3)3 + RCHO → RhCl(CO)(PPh3)2 + RH + PPh3
Upon stirring in benzene solution, RhCl(PPh3)3 converts to the poorly soluble red-colored species Rh2Cl2(PPh3)4. This conversion further demonstrates the lability of the triphenylphosphine ligands.

“We have all had the experience of finding that our reactions and perhaps even our deeds have denied beliefs we thought were ours.”
