Identification of a boron-containing intermediate in the boron tribromide mediated aryl propargyl ether cleavage reaction
An alternate reaction mechanism for the boron tribromide mediated deprotection of aryl propargyl ethers based on the isolation of a key boron-containing byproduct is proposed. On the basis of the new mechanistic insight, we discovered that HBBr2 · SMe2 can also be used for cleaving aryl propargyl ethers.
