Paper: CSIR NET December 2013 · Subject: Inorganic Chemistry · Chapter: Organometallic Compounds · Topic: Organometallic Compounds – General · Marks: 2 · Difficulty: Easy
Which of the following in NOT suitable as catalyst for hydroformylation?
(a)$\mathrm{HCo}(\mathrm{CO})_{4}$
(b)$\mathrm{HCo}(\mathrm{CO})_{3} \mathrm{PBu}_{3}$
(c)$\mathrm{HRh}(\mathrm{CO})\left(\mathrm{PPh}_{3}\right)_{3}$
(d)$\mathrm{H}_{2} \mathrm{Rh}\left(\mathrm{PPh}_{3}\right)_{2} \mathrm{Cl}$
Answer
Answer: D ✓ checked by 4AB · confidence high
Explanation
HCo(CO)₄, HCo(CO)₃PBu₃ and HRh(CO)(PPh₃)₃ are the classical hydroformylation catalysts; H₂Rh(PPh₃)₂Cl is a hydrogenation intermediate (Wilkinson), not a carbonyl catalyst.
