Alcohol rxns

[virtualmaster999]

Hi everyone!

I just want to double check on the alcohol rxns with halides to make sure I'm understanding on what carbons the reaction will form:

-HBr, HCl, and HI work on all carbons
-SOCl2 only with primary/secondary
-PBr3 is methyl, primary, secondary, and gives sn2 inversion if applicable

Is that right? Thanks in advance!

Yes,,,,,very good. Usually with primary halides, SOCl2 or PCl3 works best.....HCl is a bit slow and we use a ZnCl2 catalyst. SOCl2 may give inversion if used with pyridine, but retention if used with ether such as dioxane. Overall.....you are on target !!!!!

Hope this helps
