“…The reaction proceeded with complete regioselectivity, where a silyl group is incorporated into the central carbon of the allene moiety while an acyl group is attached to the internal position. The observed regioselectivity is identical to that observed for reactions using nonfluorinated acylsilanes . Monosubstituted allenes, including those bearing alkyl groups (i.e., 5a and 5b ), chlorides (i.e., 5c ), esters (i.e., 5d ) and imides (i.e., 5e ), successfully participated in this silylacylation reaction, providing the corresponding products in a regioselective manner.…”
