Schroeder, Sebastian published the artcileVinyl Triflimides-A Case of Assisted Vinyl Cation Formation, COA of Formula: C6H6OS, the main research area is vinyl triflimide preparation; alkyne lithium triflimide regioselective addition; alkynes; enzyme-mimicking synthesis; hydroaminosulfonation; triflimides; vinyl cations.
A new concept for selectivity control in carbocation-driven reactions was identified which allows for the chemo-, regio-, and stereoselective addition of nucleophiles to alkynes-assisted vinyl cation formation-enabled by a Li+-based supramol. framework. Mechanistic anal. of a model complex (Li2NTf2+.3H2O) confirms that solely the formation of a complex between the incoming nucleophile and the transition state of the alkyne protonation is responsible for the resulting selective N addition to the vinyl cation. Into the bargain, a general, operationally simple synthetic procedure to previously inaccessible vinyl triflimides is provided.
