When pinacol is treated with dilute H2SO4, a re-arangement reaction takes place which leads to the formation of a ketone. CH3−OH∣C∣CH3−OHC∣CH3−CH3H2SO4−−−→CH3−O∣∣C∣CH3−CH3∣C−CH5 This reaction involves re-arrangement of carbocation Step 1: CH3−OH...
The reaction of a 1:2 molar ratio of Cp3Pr with diethyl malonate in n-hexane results in the formation of {CpPr[CH(COOC2H5)2] [μ-CH(COOC2H5)2]}2. X-ray analysis demonstrates that the complex is a dimer, the two praseodymium atoms are bridged by two oxygen atoms of two ...
