What allows the conversion of cis to trans in the Ptpy2Cl2 lab?
Conversion to tetra chloride complex and addition of pyridine which has a strong trans effect
Conversion to tetra pyridine complex and addition of Cl- which has a strong trans effect
heating results in tautomerization
Acidic conditions results in tautomerization
Homework Answers
The correct answer is: conversion to tetra pyridine complex and then addition of Cl- which has a strong trans effect as compared to pyridine.
According to the concept of trans effect (which works only for squrare planar complexes) if one ligand attached is strong (i.e., has more trans effect) then the incoming ligand will be attached trans to it.
For example, when tetra pyridine platinum complex is reacted with chlorine then any one of the pyridine ligand is substituted by Cl- and in the second step as the Cl- has more trans effect then pyridine therefore it is attached on the trans position to give the desired trans product as shown below:
