CHM 233 Chapter Notes - Chapter 7-8: California Department Of Transportation, T Formation, Regioselectivity
Document Summary
Heterogeneous catalyst does not dissolve: phpd. Added in opposite planes a products = racemic mixture. Proton transfer occurs ( leaves oh) egioseleotivityhtalohydrin) Syn dihydroxylatioh syn addition of oh and oh across at bond. Breaks double bond , forms 2 fin its place. Low temp enthalpy dominates addition is favored. High temp entropy dominates elimination is favored. Thereby we use lower temps for addition. Peroxide (roor) regiosdectivetor anti - narkonikov.
