Which of the following is a precatalyst?
Option: 1
Grubb’s catalyst
Option: 2
Wilkinson’s catalyst
Option: 3
Grignard Reagent
Option: 4
Zeolites.
Answers (1)
Wilkinson’s catalyst is the square planar chloro tris(triphenylphosphine) rhodium(I) complex. This molecule is actually a precatalyst that becomes the actual catalyst when it statistically loses a triphenylphosphine ligand producing chloro bis(triphenylphosphine) rhodium(I).
Hence option 2 is correct.
