Allyl Bromide from Allyl Alcohol without H2SO4?

[FriendlyFinger]

Hi there,

Just wondering If Allyl Bromide can be made from Allyl Alcohol without using H₂SO₄.

I'm asking because I remember some bee suggesting it because he/she read it in one of their books.(sorry can't find the post).

Thanks,
Regards,

Sure, PBr₃ or Br₂/redP are both suitable alternatives to 48% HBr_(aq)/H₂SO₄. Plain 48% HBr_(aq) should also work, but probably with lowered yield.
