WebTosyl oxygen transfer and ion-neutral complex mediated electron transfer in the gas-phase fragmentation of the protonated N-phenyl p-toluenesulfonamides 来自万方喜欢 0 Alkyl tosylates are alkylating agents because tosylate is electron-withdrawing as well as a good leaving group. Tosylate is a pseudohalide. Toluenesulfonate esters undergo nucleophilic attack or elimination. Reduction of tosylate esters gives the hydrocarbon. Thus, tosylation followed by reduction allows for the deoxygenation of alcohols.
