Özet
In the presence of BF3, a series of symmetrical and unsymmetrical ethers reacted with epichlorohydrin and 2-[(benzyloxy)methyl]oxirane, two terminal epoxides, to afford 1-alkoxy-3-chloropropan-2-ol and 1-alkoxy-3-(benzyloxy)propan-2-ol. The cleavage of unsymmetrical ethers occurred via an S(N)2 or S(N)1 mechanism. Secondary epoxides did not give similar ring-opening products.
